    It could be that this feature is useful for C/C++ debugging as well.  

That would require a lot more debugging info.  Right now the debugging
info generated for C is just line numbers.  In practice that seems to
work well enough.

If debugging Bison grammars really needs this feature, then we can
provide it and use it for debugging Bison grammars.  But we would not
want to use it for C.
