No, it doesn't work for types:

void foo(alias a)() {}

void main()
{
     foo!(int)();
}

Results in:

Error: template instance foo!int does not match template declaration 
foo(alias a)()

Perhaps using the variadic template with a constraint on one element 
trick will work. Ugly, but I think that will work.
