Interesting, the docs for the join function make no guarantee about
the order of the join; however, the historic order has been first
element, second element, etc. This is unlikely to change (if for no
other reason than it would make join useless). Also, in the tests for
the Perl interpreter, there is the following code:
@x = (1, 2, 3);
if (join(':',@x) eq '1:2:3') {print "ok 1\n";} else {print "not ok 1\n";}
This seems to be a fairly strong promise that join will operate in the
expected manor.
