I agree it would be nice, and this feature is on my "to do" list. It
takes a bit of work to make the backtrace data available from Caml, though,
so don't expect this for 3.10.

Currently, you cannot. Conceivably, this would be the same mechanism
as outlined above (i.e. making backtrace data available from Caml).
However, you'd get a backtrace in terms of file names and line
numbers, which don't make that much sense for toplevel definitions.
Functions names don't really exist in compiled code.
