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.
