in reply to Destructive JAPH

I wish you good luck on your journey through the darkest corners of Perl.

Hereís a golfed and obfuscated JAPH using the DESTROY trick:

sub'DESTROY{print${+pop}}bless\$_,for',rekcah lreP rehtona tsuJ'=~/./g

The second argument of bless defaults to ::main, which is the package where subs declared without a package prefix go to. You donít need the temporary array: the SVís are still created and blessed even if map is used in void context (other built-ins, like sort, wonít let you do this). This causes them to be GCíd in reverse order, though.
