I don't think this is true. I think there would just be a whole lot of a
different type of space leak. Lazy by default is more in the spirit of
haskell. case, function, and monadic binding matching is only strict out
of necessity since they actually need to scrutinize the values and that
makes perfect sense. if anything were to change, I'd make lambda
patterns lazy. (though, I don't feel particularly strongly about that,
since a case could be made for them being just a degenerate function
binding with only one alternative)
