[Bug c++/39205] New: Warning when object syntax is used to call a static member function

2009-02-16 Thread pgrealis at yahoo-inc dot com 
I can't think of a scenario where one would want to write x.f() over X::f()
when f() is static.  I'd like a warning for this so I can catch with -Werror.

I never claimed anything different.  Is your argument that no warning should be
issued for "perfectly valid C++"?

"(int)1.5" is perfectly valid C++, yet -Wold-style-cast will emit a warning for
its use.

To close as INVALID, please refute the following:
