Can a simple a==b 'hang' in and endless loop?

The point is to find a way to create in Python two indentifiers a and b 
without manipulating any of the __eq__ and to __eq__ related functions 
in a way, that the simple
   if a==b: print 'a==b'
statement results in an endless loop.
To my knowledge this is not possible to achieve in C, but is probably 
achievable in Python.
