`from __past__ import print_statement`: a Dadaist Rejection of Python 2 vs 3
summary
Presents a working, pip-installable hack that patches a running CPython by inserting a runtime C-Python trampoline to override eval behavior, plus a module that implements global read watches (demo breaks arithmetic like 1+1==4). Rewrites grammar to add syntax extensions so print becomes a statement again in Python 3, works on Linux and macOS but not Windows, misses edge cases (angle-bracket redirection and trailing-comma suppression) and deliberately perverse rather than production-ready.
