Re^2: Interview Questions

the Schwartzian transform

Do they get extra points for knowing there is a drink named the Schwartzian Transform? (Which, like the transform itself, wasn't named by me.)

the difference between my, our, and local

Do they get extra points for knowing the difference between "our" and "use vars"?

closures

Do they extra points if they can demonstrate anonymous subs that aren't closures, or closures that aren't anonymous subs?

my $this_is_an_anonymous_sub_that_is_not_a_closure = sub { print "hell
+o" };

BEGIN {
  my $message = "this is a closure that is not an anonymous sub";
  sub here_it_is {
    print "$message\n";
  }
}

To the peanut gallery, its not being inside the BEGIN block that matters. This too is a closure: `{ my $msg = "Hi randal!"; sub hi { print "$msg\n"; } }` [download] (Yes merlyn, I know you know this... My coworker that just pointed out your message does not.)	[reply] [d/l]
