import std.stdio;

template T(alias X) {
}

void main() {
    writeln(typeid(typeof(T!int)));
}

dmd 2.048 on linux produces an error for the above code.

Error: template instance T!(int) does not match template declaration T(alias X)

Built-in primitive types cannot be used as template alias parameters. Structs
and classes work well.
