Thank you Martin, Just to be sure, is that expected behaviour? Or should I expect to have the a more precise instantiation point? --- /Users/pinver/dlang/dmd-2.095.0-beta.1/osx/bin/dmd -i -g -debug src/foo.d /Users/pinver/dlang/dmd-2.095.0-beta.1/osx/bin/../../src/phobos std/traits.d(3727): Deprecation: function std.typecons.Nullable!long.Nullable.get_ is deprecated - Implicit conversion with alias Nullable.get this will be removed after 2.096.

So, this is a constant problem since this deprecation was introduced. What is happening is that some speculative compilation is checking something via the get function. It might not make a difference, but the error message is useless (who knows where that traits call is triggered). Most likely, it doesn't change anything. Therefore when you turn on the deprecation as an error, it doesn't affect compilation, it just fails in the speculation instead of succeeds. But the ultimate result doesn't actually change anything. I can't wait until this deprecation has been finalized, because I hate seeing seas of deprecation messages I can't do anything about. 2.097 cannot come soon enough... I'm also looking forward to being able to print Nullable!string values inside structs without an exception being thrown. -Steve

FYI, v2.095.0 *should* print the instantiation trace, so you can actually track down where it comes from. And the reason DMD now shows the trace is exactly because of this deprecation.

FYI, in theory we could use `__traits(isDeprecated)` to silence this. But I haven't looked at the code myself.

The point is that the deprecation is coming from an external library, it would be great to have the precise instantiation point in that source code, so I was wondering if that dmd improvement [1] should print a more detailed trace. [1] https://dlang.org/changelog/2.095.0.html#deprecation-context

It does print a detailed stack trace (up to the first symbol that is not a template) if you don't use `-de`. If you use `-de`, since the checks in Phobos are `is(typeof(n.toString()))` or `__traits(compiles, n.toString())`, then it just changes whether or not the code compiles, and as a result changes the output of the program. A trivial example: ``` import std.stdio, std.typecons; struct Foo { deprecated string toString() const { return "Oops"; } } void main () { writefln("%s", Foo.init); } ``` Will print, with v2.094.2 or before (dmd -run): ``` /usr/local/opt/dmd/include/dlang/dmd/std/format.d(3921): Deprecation: function foo.Foo.toString is deprecated /usr/local/opt/dmd/include/dlang/dmd/std/format.d(4053): Deprecation: function foo.Foo.toString is deprecated Oops ``` Not great. If you use `dmd -de -run`, you'll get: ``` Foo() ``` Notice the deprecations are gone, but so is the usage of the `toString` method. Using DMD v2.095.0-beta.1 with `-de` should give you the same output, but without `-de`: ``` % ~/dlang/dmd-2.095.0-beta.1/osx/bin/dmd -run foo.d /Users/geod24/dlang/dmd-2.095.0-beta.1/osx/bin/../../src/phobos std/format.d(3921): Deprecation: function foo.Foo.toString is deprecated /Users/geod24/dlang/dmd-2.095.0-beta.1/osx/bin/../../src/phobos std/format.d(4420): instantiated from here: hasToString!(Foo, char) /Users/geod24/dlang/dmd-2.095.0-beta.1/osx/bin/../../src/phobos std/format.d(4053): Deprecation: function foo.Foo.toString is deprecated /Users/geod24/dlang/dmd-2.095.0-beta.1/osx/bin/../../src/phobos std/format.d(4430): instantiated from here: formatObject!(LockingTextWriter, Foo, char) /Users/geod24/dlang/dmd-2.095.0-beta.1/osx/bin/../../src/phobos std/format.d(1875): instantiated from here: formatValueImpl!(LockingTextWriter, Foo, char) /Users/geod24/dlang/dmd-2.095.0-beta.1/osx/bin/../../src/phobo /std/format.d(576): instantiated from here: formatValue!(LockingTextWriter, Foo, char) /Users/geod24/dlang/dmd-2.095.0-beta.1/osx/bin/../../src/phobo /std/stdio.d(1661): ...

Unfortunately it doesn't fix the exact case you found, it was a byproduct of working on your test case. And I don't think I'll have time to get to it before the release (which is scheduled January 1st).

When I look at dub's commits, I see a recent commit to tag version 1.24.0-rc1. It might be useful to mention the latest version of dub somewhere in the change log as well, at least to the extent that the dub releases will be coinciding with the DMD ones.

It might be a good idea for someone to at least do triage on this regression I found before release: https://issues.dlang.org/show_bug.cgi?id=21513 The symptoms weren't too bad in my case (an easily worked around segmentation fault), however it seems like the kind of thing that might cause silent memory corruption in another context?
