BrowserUK, I follow lines 1-3 (except for the ";;"). But I'm not clear on that last statement. Should "pp" print out the hash reference like in your last line? I can't find documentation for that usage, and I can't make my the script print. "print Dumper($href);" works for me.

(except for the ";;")

Two adjacent semi-colons act exactly the same as a single semicolon. Effectively there is a blank statement (noop) between them.

The difference is that my REPL accumulates what I type until I finish a line with ;; at which point it executes everything I've typed so far as a single chunk of code.
