           Summary: Class method hidden by another one warning
           Product: D
           Version: future
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Keywords: diagnostic
          Severity: normal
          Priority: P2
         Component: DMD

This D2 program:


class A {
  void foo(A a) {}
}
class B : A { // line 4
  void foo(B b) {}
}
void main() {}


It compiles with no problems with dmd v2.046:
dmd test.d

But if I compile it with:
dmd -w test.d

I receive a compile error:
test.d(4): Error: class test.B test.A.foo(A a) is hidden by B


In my opinion that error message can be improved in something like this (that also informs the programmer that this error comes from the -w switch):

test.d(4): Warning: class method test.A.foo(A a) is hidden by test.B.foo(B b)


I presume this warning is useful because it can avoid bugs. If it is important it can become a true error, that doesn't need -w to show up (see also bug 3836 ).

DMD 2.054beta without -w prints this:

test.d(4): Error: class test.B use of test.A.foo(A a) hidden by B is deprecated

The error message may also suggest the use of "alias" to solve this problem.
