perl <= 5.6 core

Hi,

while playing with ton-s winning golf entry, I noticed

perl -le '@q=(1,2);map{print $_ for @q}@q'

dumps core for me in 5.6 and 5.00503. Now I really wonder why this might
be, it sure looks sane to me. Does anybody have an idea? :)

It doesn't core if @q contains only one element...

CU,

how to arrange it so that what you want is composed of operations that
the bureaucracy supports.  In addition, in any bureaucracy, there is
always *someone* whose job is to approve violations of the rules.
