If you compile (with perlcc -b) this lovely perl1 code:
open(TC, "< /etc/termcap");
while (<TC>) {
split(/:/, $_);
for ($i = 0; $i <= $#_; $i++) {
$seen{ $_[$i] }++;
}
}
And then try to uncompile it, this is what happens:
% perl -MO=Deparse,-p /tmp/tcap.pbc
open(TC, '< /etc/termcap');
while (defined(($_ = <TC>))) {
split(/:/, $_, 0);
($i = 0);
while (($i <= $#_)) {
(++$seen{$_[$i]});
}
continue {
(++$i)
}
}
/tmp/tcap.pbc syntax OK

which looks like something I saw yesterday.
