New Revision: 22103
Modified:
pypy/dist/pypy/lib/pyontology/pyontology.py
pypy/dist/pypy/lib/pyontology/test/test_ontology.py
Log:
Refactor the way "type" works. The goal is to get rid of the make_var function/cludge. To be able to do this I need to get rid of BinaryExpressions. Changed the tests accordingly
