This sounds like a better idea.  One should be able to hook Bison up
to Emacs gud-mode, for example; or to Eclipse.

Right, that would be the normal case.

We could let the user selectively execute parts of semantic
actions, by giving them a value that their actions could inspect.
This is a bit like how $(MAKE) works when you type 'make -n'.
