That's because it isn't available in the default perl 5.8.8: `> perl -Mstrict -w -e'my $f; print ($f // "something\n")' print (...) interpreted as function at -e line 1. Search pattern not terminated at -e line 1.` [download] "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply] [d/l]

Thanks for the clue. I did not realize that the defined-or patch is unconditionally applied these days to Perl 5.8.8 port (as in FreeBSD lang/perl5.8 port).	[reply]
