> Note clang warns but its warning is not so clear:

> [-Wpredefined-identifier-outside-function]
> void bar (const char *s = __FUNCTION__) { puts (s); }
> ^
> <source>:5:27: warning: predefined identifier is only valid inside function
> [-Wpredefined-identifier-outside-function]
> void baz (const char *s = __PRETTY_FUNCTION__) { puts (s); }
> ^

> At least MSVC is clear on what is going on:
> <source>(4): error C2457: '__FUNCTION__': predefined macro cannot appear
> outside of a function body
