```C++
template <class T, std::enable_if_t<std::is_const_v<T>,bool> = true>
void foo() {}
int a = foo<const int>();
```
and
```C++
template <class T, std::enable_if_t<::std::is_const_v<T>,bool> = true>
void foo() {}
int a = foo<const int>();
```

will produce different mangling.
They first will produce _Z3fooIKiTnNSt9enable_ifIXsr3stdE10is_const_vIT_EEbE4typeELb1EEvv and the second will produce _Z3fooIKiTnNSt9enable_ifIXgssr3stdE10is_const_vIT_EEbE4typeELb1EEvv
This also introduces an ABI breaking with GCC as GCC produces _Z3fooIKiLb1EEvv
