Sorry, for almost all BIF's, there is no "internal" field
that can be debugged.  In some cases, the BIF simply results
in a value pushed on the run-time stack.  In others, the
result is placed in some compiler generated temporary (or set
of temporaries), but the name is not debuggable.  Even if
these temps were debuggable, the temps are re-used, sometimes
even within the same statement.  As I said before, substantial
work would be needed in both the compiler and debugger to
allow debugging of BIF results, so this is not likely to
happen.
