Consider:
struct A(alias pred) {}
void fun(alias pred)(A!(pred) ax) {}
void main()
{
A!("x") a;
fun(a);
}
Result:
Error: template test.fun(alias pred) does not match any function template
declaration
Error: template test.fun(alias pred) cannot deduce template function from
argument types !()(A!(""))
The code works as expected if the alias is replaced with a type parameter.
