template<typename T>
struct A {
};
namespace H {
template<typename T>
struct B {};
};
A a;
H::B b;
int main() {
A a;
H::B b;
return 0;
}
produces:
~/ootbc/common/test/src$ g++ foo.cc
foo.cc:10: error: `A' does not name a type
foo.cc:11: error: expected constructor, destructor, or type conversion before "b"
foo.cc:11: error: expected `,' or `;' before "b"
foo.cc: In function `int main()':
foo.cc:14: error: missing template arguments before "a"
foo.cc:14: error: expected `;' before "a"
foo.cc:15: error: missing template arguments before "b"
foo.cc:15: error: expected `;' before "b"
Oddly, the diagnostic produced when the error is inside a function is different from (and better than) that for the same error in file scope. And why the (bad) messages differ when the template is or is not namespace-qualified beats me.
Lastly, the missing ";" message seems redundant in all cases.
