Given that we have '=:=' and 'orelse' and 'length',
it wouldn't be much of a change to Erlang to allow
member(C, " \t\r\n") in a guard.

Syntax we _already_ have would be even better.
I looked at the Mochiweb code recently. My first reaction
was to ask for member/2 in guards; my second reaction was
that character classification predicates would probably be
more to the point.
But none of this really has anything to do with joins.
