On further thought, concatenateAll: and such probably deserve a more 
succinct selector. The equivalent of this is "join" in 
perl/python(/ruby? I forget), although Common Lisp / Dylan just call it 
"concatenate".

Perhaps ;* would make sense since current binary concatenation is ; (or 
;; if you're lazy ;). I'd prefer not to use join: as it'd be confusing 
and probably overloaded in different ways. Either way, the separator 
should probably be an optional keyword, which would not be difficult to 
do. Does that sound right, or too confusing? Ideas?
