there is a subtle distinction in those two. the first should be a syntax
error. the second isn't an error but isn't needed. you could just
as easily do ( @a, @b, @c )[-1].
and the equivilent works in perl5. dumb, but it works.
perl -le 'print pop( @{[qw(a b c)]} )'
c
and i haven't seen anything in perl6 that drastically changes the
semantics of lists and arrays from perl5. so the current definitions we
have been tossing about should suffice.
minor variation:
an array (anon or named) is a container that holds a list. the
array container itself can be modified. containers can stay
alive as long as you want.
a list is a ordered bag of values. it is alive
only where it is created in the current expression. the list
cannot be modified.
