This code:


template isBar(T) {
    enum isBar = false;
}
template Foo(T) if (isBar!T) {
}
void main() {
    alias F = Foo!int;
}


Gives (before this patch):

temp.d(7): Error: template instance Foo!(int) does not match template
declaration Foo(T) if (isBar!(T))

isn't it better to use that ddoc logic to generate a simpler error message
similar to:

temp.d(7): Error: template instance Foo!(int) does not match template
declaration Foo(T) if (isBar!T)
