None of the strip or split functions in Phobos deal with anything other than 
whitespace. splitter is more general, but there is no stripper (which would 
arguably be a horrible name for a function anyway). However, that's 
essentially what find does, albeit with the predicate effectively being 
reversed. e.g.

find!"a != ';'"(";;;;;blah");
