Comment (by claus):

 my personal preference would be to do away with the special case of
 printing bind results completely (just as with let, one can do :show
 bindings and show any particular variable one might want to have
 evaluated). since there is an option, and i can switch it off, it doesn't
 bother me too much, but the printing should be all or nothing (and
 probably using the new :print, instead of show), not "if there is exactly
 one variable..".

 there should also be an option that specifies whether or not the result of
 IO monads is shown (i recall that it can be confusing if those results are
 not shown, but it can be annoying that they are always shown). an option,
 on by default, would be nicer than having to resort to things like 'let
 void m = m >> return ()'.
