Y’know, I think that this is a fantastic thing that you’re doing, and I hope that you’ll write more like it.   Part of the real problem with a subject about which much could be said ... is that we tend to say it all.   But when you say, in your own words and terms, what you recently needed to know and what you found out to be true ... that’s the best kind of tutorial.   More details can and will be added.

I came to Perl from much-more explicitly object-oriented languages, and from the experience of having to write assembler-level code that interfaced with the “guts” of several of them.   (All of these pretty-much resolved the object issues at compile-time.)   When I encountered Perl and bless and all-of-that, I wondered, “where’s the rest of it?”   When the lights started coming on, I meant to write those thoughts down at that time, but never did.   I couldn’t write them the same way now.   Thanks for your excellent contribution.
