in reply to One of these things is not like the others...

From the documentation for push.
Starting with Perl 5.14, "push" can take a scalar EXPR, which must hold a reference to an unblessed array. The argument will be dereferenced automatically. This aspect of "push" is considered highly experimental. The exact behaviour may change in a future version of Perl.
This is probably the answer and note that the docs say it is experimental and may change in the future.

[LanX]: yes
[sierpinski]: yeah I guess $list is a reference.. yeah
[sierpinski]: why is it the last index and not the first? because the length of the array becomes the index?
[sierpinski]: thanks LanX that helps
[haukex]: the first index is always 0 - $#array gives you the last index in @array
[sierpinski]: gotcha, thanks
[LanX]: length = last index +1
