  • Just like people never seeing OO or declarative solutions to problems if all they've ever used is FP.

    If you've come from a background where you take source files, compile them, and get running code out the other side then making that mental leap of going in the other direction is hard.
    • The potentially fatal flaw in the plan:

      #!/usr/bin/perl -l

      use strict;
      use warnings;


      sub a {
          print 'whoops!';

      sub b {
          no warnings 'redefine';
          *a = sub {
              print "hi there!";

      This is obvious in retrospect. I can't imagine this would be easy to get around.
