This has nothing to do with pragmas. Pragmas do not change execution
behavior of a compiled method. Also pragmas are in the source code, so
you cannot add them without changing the source.
There was some work on annotations by Marcus, this goes more into the
direction you are looking for.
What I would do is to replace a compiled method with a custom object
that implements #run:with:in: and that opens a debugger at the right
place.
Yes, that's more or less how VisualAge does it. See DbgBreakpointedMethod, a�variable Subclass of�CompiledMethod.
