void f(alias a)() if (is(typeof(a()))) {}
void main()
{
f!(x => blarg);
}
This gives the error:
foo.d(5): Error: template instance f!((x) => blarg) does not match template
declaration f(alias a)() if (is(typeof(a())))
Ideally, the error would be:
foo.d(5): Error: undeclared identifier 'blarg'
This comes up all the time when using predicates on Phobos functions when you
forget an import or just have a typo.
