..."dereferencing" a variable...
It isn't dereferencing a 'variable' but a subroutine.
"Take the value of $functions{$doit} and treat it as a sub name" Is that about right?
More or less, yeah. But I have to admit that my powers of syntax explaining are pretty poor, I understand in my head what is going on but I don't want to lead you down the garden path with my crap explanations. There are many people here who could explain far more eloquently what is going on and hopefully one of them will step in to help both of us ;)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • Outside of code tags, you may need to use entities for some characters:
