Reported by @meh in github. https://github.com/D-Programming-Language/dmd/pull/1006#issuecomment-6646067 > This pull broke something. > > I didn't manage to get a reduced testcase but I get this error: > > nucular/protocols/http/headers.d(65): Error: template std.algorithm.countUntil does not match any function template declaration > /usr/include/d/std/algorithm.d(3801): Error: template std.algorithm.countUntil cannot deduce template function from argument types !(__lambda4)(Header[]) > nucular/protocols/http/headers.d(65): Error: template instance countUntil!(__lambda4) errors instantiating template > When compiling _internal = _internal.remove(_internal.countUntil!(a => a.name == name));. > > The incriminating commit is 6cf404d, before that it compiles properly. Reduced test case: void main() { bool b; foo!(a => b)(); } void foo(alias pred)() if (is(typeof(pred(1)) == bool)) {}
