True, I forgot mentioning that. Simplified example:

template bar(T...) {
    alias bar = void;
}

void foo()() {}

void main() {
    assert(!__traits(compiles, {struct A{bar!foo tmp;}}));
    assert(!is(typeof({struct A{bar!foo tmp;}})));
}

Also worth noting that these work (note the lack of a surrounding struct):

    assert(!__traits(compiles, {bar!foo tmp;}));
    assert(!is(typeof({bar!foo tmp;})));

I updated the summary to reflect this.
