If you try to call .toString directly on a const(S), you get
the following error:
onlineapp.d(27): Error: onlineapp.S.toString called with
argument types () const matches both:
onlineapp.d(9): onlineapp.S.toString() const
and:
onlineapp.d(13): onlineapp.S.toString() const
Sure, but that's too late. IMHO the compiler should detect
duplicate
definitions (probably concealing a program error) regardless
whether
the method is called. There is a difference between calls which
match
two or more functions and duplicate definitions. Isn't it?
Other compilers for other languages complain loud and clear:
```ddcpp.cc
template<typename T>
struct X {
int foo ()
{
return 0;
}
int foo ()
{
return 0;
}
};
```
result from clang++:
ddcpp.cc:7:8: error: class member cannot be redeclared
int foo ()
^
ddcpp.cc:3:8: note: previous declaration is here
int foo ()

ddcpp.cc:7:8: error: redefinition of 'foo'
int foo ()
