I'd actually enjoy that :) However, I first really understood objects from learning how to create them from closures in Scheme. And I'm not sure how many object systems built from array reference hacks in Tcl I've looked at.
But probably not what most people are probably looking for when they are first trying to understand something like Perl or Ruby.
Actually (and sadly) for some jobs with Perl that involve codebases older than 2007. That material would be useful. Because, like the languages you mention, deriving object systems from Perl5's rough axioms, was at one point something of a hobby for people.
