I revived the deprecation cycle at https://github.com/dlang/dmd/pull/8429.
Please see the PR for the motivation and chime in if the summary there doesn't
match your opinion / use cases.

So C clearly doesn't support function overloads, but D provides for better type
checking and generally expects as much.

I think it would be nice to allow D to specify function overloads if the C call
is ultimately the same (parameter sizes and such).

This way in D a function can be specified to accept pointer types of A, B, and
C rather than needing to be a void* as it is defined in C. I think it is
similar to marking a parameter const even though it has no meaning to C and
isn't actually enforced. This also appears to be how DWT has utilized
definitions.

I've realized that my upgrade to dxml and DWT for an application has cause my
application to not compile on any of the D compilers, so a solution here would
be nice or for [18475] to be fixed on 2.078.

Yes, I actually have a class. I just tried to reduce the test case as much as
possible.
