in reply to Perl Python Partial Polyglot

Curiously, in this Stack Exchange Obfuscated Hello World Contest, there were no Perl entries and the winning entry was written in Python -- here's an explanation. Nowadays, it's easy to find tutorials on Obfuscated Python.

Python has become more popular than Perl for golf too, as mentioned in The golf course looks great, my swing feels good, I like my chances (Part IV) in the "Which is the Most Popular Golfing Language?" section.

    From the "explanation" you linked above I was impressed by this:

    "o" from the second letter of bool: True.__class__.__name__1

    I thought one can extend this to cause error messages in $! (in Perl), e.g. "No such file or directory" and use single chars from them to try and form an obfuscated string. e.g. perl -e 'open(IN, "<", "");print @{[split(//,$!)]}[8,1,1,10,9,3,6];'

    Have I re-invented the wheel or is this my first obfuscated Perl signature?

      I guess ref() would be pretty similar.

      perl -e 'print @{[split //,ref(\$.)]}[-1,-2,0,1,-2,-3]'

    They almost all resort to using lambda though, which I ended up doing also. Not as fun/creative as obfuscated Perl.
