With 1.9 being able to specify local variables in the argument
list and if matz does something about closures holding all
variables in the scope, I doubt you'll find the "need".  If
there are too many issues (i.e. compatibility problems) with
having closures not hold all variables in the scope, I think
having a non-closure block that didn't have that baggage
(excess memory usage) would be compelling.  In the majority of
cases I use blocks, I don't need them to be closures.
