           Summary: [2.063] Fix for issue 3449 causes very unclear error
                    messages
           Product: D
           Version: future
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD

        ReportedBy: doob me.com



Except that the fix for issue 3449 causes existing code to silently change
behavior. It can also cause very unclear and confusing error messages. I hit a
couple of these when trying to compile Tango.

Example of error messages I got:

* tango/io/selector/SelectSelector.d(156): Error: function
tango.io.selector.SelectSelector.HandleSet.opAssign is not callable because it
is annotated with  disable

https://github.com/SiegeLord/Tango-D2/blob/d2port/tango/io/selector/SelectSelector.d#L156

The code doesn't use  disable at all. "opAssign" is not overloaded. It's very
confusing that keywords and functions that don't exist in the source code are
mentioned.

* Error: cannot modify struct this HandleSet with immutable members

No file or line information.

I opened bug 10160 to fix the strange error message.
