std.algorithm.among

[bearophile via Digitalmars-d-learn]

The idea of not making std.algorithm.among!() a predicate was not 
so good:

void main() {
    import std.stdio, std.algorithm;
    auto s = "hello how\nare you";
    s.until!(c => c.among!('\n', '\r')).writeln;
}


(A normal workaround is to use !!c.among!).
