Pipe-ifying Python: The how and why of interpreter hacking
summary
Adds a concrete pipe operator to CPython by changing token and grammar files, rewriting the parse rule to be recursive, and lowering pipes into normal call nodes so translation and runtime need no new opcodes. The patch is small: +38 −2 lines (generated boilerplate larger). Edits touch grammar/python and Grammar/tokens, plus a short AST transform; unparse via ast.unparse produces plain Python without pipes for compatibility. Demo uses built CPython so examples actually run.
