Right.  The thing is that using reflection data rather than debugging
info

*  works without debugging info,
*  doesn't require additional processes to be created,
*  removes a dependency on external tools that may not be present and
   occasionally don't do what we want.

Perhaps the right thing to do is to make thr choice configurable or
have some time of runtime auto-detection.  Could be tricky, though.
