A bit OT, but I have always wondered why you end statements with 2 semi-colons. I know there's nothing syntactically wrong with it.

    My REPL accepts multiple input lines by the expedient of accumulating them until a line is ended with a double semicolon.

    An unedited C&P from my REPL:

    [0] Perl> sub giveList { return 1 .. 10; } print +( giveList() )[ 2 ]; ;; 3 [0] Perl>

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)
    In the absence of evidence, opinion is indistinguishable from prejudice.
