   You mean, like this:

   >>> from openmath import *
   >>> i = convert.to_openmath(1)
   >>> i
   OMInteger(integer=1, id=None)
   >>> convert.to_python(i)
   1
   >>> convert.register_to_python(openmath.OMInteger, lambda x: "Hello")
   >>> convert.to_python(i)
   'Hello'

   Ah, right, it's already possible to customize it. The code itself could use it, replacing
   the last 2 lines of:

   def to_python(omobj):
       """ Convert OpenMath object to Python """
       if omobj.__class__ in _conv_to_py:
           return _conv_to_py[omobj.__class__](omobj)
       elif isinstance(omobj, om.OMInteger):
           return omobj.integer
   

   by a call to register_to_python at initialization time.
