I want to make an anonymous subclass, or a copy of (either way) a subclass
I've been googling around looking for an example of an anonymous subclass. I
haven't had luck with anything I've found. It's possible that there's
something I'm missing conceptually, because I've read through various
examples, but they all seem to do directly with Behavior or Class. I tried
various combinations of things with both of the approaches I found. Some of
them hung the image, with others the #primitiveChangeClassTo: would fail. I
read the comment there, and am aware that using it is reckless behavior.
I see that Smalltalk compactClassesArray gives me a list of the compact
classes. I don't seem to understand the format part. I've noticed that
certain classes (e.g. Array) are declared "variable subclasses" but that's
it. I googled and didn't turn up anything that seemed to help me grok it.
Class format. "answers 148" Head scratch; think. ^self shrug
