This invalid code:

void foo(T)(int) if (is(T == int)) {}
void main() { alias f = foo!string; }

Outputs:

test.d(2): Error: template instance foo!(string) foo!(string) does not match
template declaration foo(T)(int) if (is(T == int))


"foo!(string)" is displayed twice - it's redundant. Should be:

test.d(2): Error: template instance foo!(string) does not match template
declaration foo(T)(int) if (is(T == int))
