Thanks Dave. I wasn't aware of what SlangBrowser was...I always saw it in
the VMMaker repo but I didn't know what it was until today. Cool project. I
really like the idea.
It would be awesome to extendt it so that it can not only supports
ObjectMemory/Interpreter/Plugins  but also CompiledMethods of those classes

For example,  (Interpreter >>#lookupInMethodCacheSel:class:)  asCString
that would be lovely :)

Just for the record (if you want to include it in the wiki), in order to
make it work (the asCString) I needed to first load MemoryAccess because it
is used in VMMaker class >>cCodeGenerator: aClass inCache: cache inlined:

You can...or document that on the wiki or maybe add a Smalltalk at:   ?

Anyway, how much effort do you think it could be to adapt at least the
asCString to the new Cog versions ?    because this is a nice feature for
when you are learning
