7 | # Do not rely on features found only in more modern Perls here, as some CPAN |
8 | # distributions copy this file and must operate on older Perls. Similarly, keep | |
9 | # things, simple as this may be run under fairly broken circumstances. For | |
c42fde61 | 10 | # example, increment ($x++) has a certain amount of cleverness for things like |
485f531e DL |
11 | # |
12 | # $x = 'zz'; | |
13 | # $x++; # $x eq 'aaa'; | |
69026470 | 14 | # |
c42fde61 | 15 | # This stands more chance of breaking than just a simple |
485f531e DL |
16 | # |
17 | # $x = $x + 1 | |
18 | # | |
19 | # In this file, we use the latter "Baby Perl" approach, and increment | |
20 | # will be worked over by t/op/inc.t | |
