This raises the question of how FOR and WHILE should be handled with implicit return. I suppose, if either of those is the last form in a function, the function should just return NIL?
Also, we can extend PS LOOP to do much as CL's LOOP does with intra-loop RETURNs. But we should hold off on this till implicit return is working in PS.

Hi Vladimir,
You'll probably want to handle FOR, WHILE separately in the RETURN special form, but I think this works for our purposes with the existing support for PROGN.
Generally, I think that the implicit return mechanism should try its utmost to avoid generating JS syntax errors.
