digitalmars.D - Seas of errors from DMD

This is a recent "fix":

but I suggest to revert it, or improve it significantly, because I am seeing
avalanches of error messages, that slow down my compilation-fix-run cycle and
are useless to me and unreadable.

A little example code:
http://codepad.org/UvlfYO1t

The bug is at line 46, the "in" before "T function":
void report(T)(in T[] r, in T function(T) pure f, ...

About half of the generated error messages, codepad shows only about the first
520 lines of errors, but it generates 1029 long lines of errors like this:

That is expected (and intended). It will flush out a lot of pre-existing bugs which have been hidden up to now. Note that inside an is(typeof()), all these errors HAVE always been generated! We want to get rid of them all. This was deliberately introduced at the beginning of a release cycle, you won't see this behaviour in a release. Please enter bug reports for anything you find.

Cannot reproduce. I just get: --- bug.d(67): Error: template bug.report(T) cannot deduce template function from argument types !()(real[],real function(real x) pure nothrow) ---
