=> How does it reorder "loop"? :-)
That's easy. It re-orders it as "loop". :-)
To see the difference between "loop" and "loop", one has to
be in the loop. Or loopy. :-)
Anyway, to satisfy the sceptics (and, of course, for ObPerl)
here is a one-liner that shows the difference, using sort():
|| % perl -le '$, = ", "; @x = qw(loop loop); \
|| &ps(@x); &ps(reverse @x); sub ps {print sort @_}'
|| loop, loop
|| loop, loop
|| %
Clearly, sort() swaps "loop" with "loop" in the first
invocation, but in the second invocation, "loop" already
precedes "loop". :-)
