I don't see why you can't just write a function that
loops over the results and calls the user's reversal
function for each one.

   def reverse_multiple(skill, resx_list, opnds):
     for resx in rex_list:
       skill.reverse(resx, opnds)

There's no need to macro-expand this code into every
reversal function, when it can be done once as part of
the framework that calls the reversal functions.
