A bilingual JAPH. Valid code in Perl & brainf***!

We have now highlighted the Perl code.

This code implements a limited Brainf***
interpreter that only can deal with "+",
"-" and ".". It reads the Brainf*** code
contained in the list quoted by qw!...!
and interprets it.

A more verbose version would look like:

$/ = 0;
# next line is equivalent to:
# for qw!Brainf*** code string!
foreach $_ (Brainf*** code words) {
    # next line is equivalent to:
    # /[+-]/&&
    if (/[+-]/) {
        # next 2 lines are equivalent to:
        # eval "\$/$_$_";
        $/ += 1 if /\+/;
        $/ -= 1 if /\-/;
    # next 5 lines are equivalent to:
    # ||/\x2e/&&print chr$/
    } elsif (/\./) {
        print (chr($/));
    } else {
        # ignore other chars
    }
}
