We are working on an interpreted language which is very similar to
Smalltalk, but with some type protection and 4GL type syntax.

We will want to be adding some debugging support, hopefully written in the
language itself.

I've been thinking around the issues, and the following, at least, emerge:

i) setting breakpoints
ii) stepping through code
iii) inspecting object variables
iv) inspecting scoped local variables.

Can anyone share their experience of designing for debuggers for an
interpreter? Does anyone know of any papers on this subject, especially
on the implementation of Smalltalk debuggers.
