Thanks, it's useful. There's std.string.split but it takes only one 
delimiter. It'd be nice to have it as an overload that takes any range 
of delims. Yet, a delim can be a string (an array) and there would be 
problems how to understand split(..., "://"). So I suggest calling it 
splitBy to disambiguate. Like it?
