The quality of error messages is always a problem, but numbers
won't fix that. (Been there, done that, too. Numbering doesn't
clarify things.)
I think we'll just have to agree to disagree on that point. I've
found VC++ error numbers invaluable whenever I confront a
confusing error. There are often examples of what cause the error
and how to fix it.
What we have been doing is, when lousy messages are identified,
a PR is often produced to improve it. That's how these things
get better, one message at a time.
Yeah, that is true (even if error numbers were adopted).
The error message I've always hated the most is "does not match
any function template declaration" but error numbers wouldn't
help with that one because the error is obvious but what exactly
caused it isn't. I kind of wrote out an idea for one way it could
be improved awhile back (basically just reformatting the message
so you can point an arrow at the failing template constraint).

It's dated though because CyberShadow has since added column
numbers and using that would be prefered, I think. Just
underlining failing template constraint would do wonders.
Combined with colored output and deciphering this error message
would be almost pleasant.
