return is hard to implement, since each expression is building its own expression, so you need to forward it along the whole chain. Exceptions could also be used, but it's not very nice.
Sorry, I meant "since each expression is building its own function" here.
In principle that shouldn't limit anything, right? There's no reason that "a, b" (or any other lambda expression containing a and b) has to be evaluated via straightforward evaluations of a and b... I think.
It can be done, but it would require a bit of work since it would affect the whole evaluation system.
