chameleon benchmark fails on the master branch of Python #47
Description
performance 0.7.0 fails on the master branch of Python (future Python 3.8), because Chameleon has no handler for AST node type ast.Constant.
performance 0.7.0 uses Chameleon 3.4. I see two options:
- Disable/remove the benchmark
- Fix Chameleon, wait for a new release, upgrade Chameleon in performance
