[squeak-dev] Where does the compiler handle the "local bindings" of workspaces?

Hi Karl,

Yes - my first idea was to ask here what I needed to change in my
class TerseGuideHelp to make the "workspace" of its help browser use
dynamic biding of variables... but then I spent some hours trying to
find the answer myself, and I stumbled on a more low-level question
that I found much more askworthy...

I did that. Are these differences obvious to a trained eye? They
weren't to me.

> 'bindings'.

This may be a pointer to searching tools that I need to learn. I saw
that if I click on "variables" and then on "bindings" I get a list of
the methods in Workspace that access the variable "bindings"... I also
tried to fileOut the class Workspace and to read it in Emacs, and I
found the same occurrences.

Here is an educated guess. Is the method "hasBindingOf:" the main
piece needed to make a mini-workspace support dynamic variables? If
so, how, exactly? Is there a part of the compiler that calls
"hasBindingOf:" when it sees an unknown variable? I couldn't find
