I consider this a useful feature. I do not see a reason why C needs to
make a difference between these two cases:
void f1(void);
void f2(void) { f1(); return }
char f3(void);
char f4(void) { return f4(); }
I prefer to use f1/f2 in the same manner as f3/f4.
And apart from templates, this is also useful with macros. E.g. when the
return type is a macro. The alternative is lots of ugly #if constructions
to see if the return type happens to be void and insert different code
accordingly.
