typename resolution in cases of ambiguity
- by parapura rajkumar
I was playing with Visual Studio and templates.
Consider this code
struct Foo
{
struct Bar
{
};
static const int Bar=42;
};
template<typename T>
void MyFunction()
{
typename T::Bar f;
}
int main()
{
MyFunction<Foo>();
return 0;
}
When I compile this is either Visual Studio 2008 and 11, I get the following error
error C2146: syntax error : missing ';' before identifier 'f'
Is Visual Studio correct in this regard ? Is the code violating any standards ?
If I change the code to
struct Foo
{
struct Bar
{
};
static const int Bar=42;
};
void SecondFunction( const int& )
{
}
template<typename T>
void MyFunction()
{
SecondFunction( T::Bar );
}
int main()
{
MyFunction<Foo>();
return 0;
}
it compiles without any warnings. In Foo::BLAH a member preferred over a type in case of conflicts ?
