Thanks Brett, that cleared everything up for me! And indeed it is what I'm thinking of doing for Jython (Minimal nodes for the compiler and parallel PyObjects for Python). -Frank ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/ma

Re: [Python-Dev] AST optimizer implemented in Python

Implementations are currently required to *have* an AST (or else declare non compliance with that particular flag to compile). They're definitely not required to have the *same* AST, thus all AST manipulation, like bytecode manipulation, is necessarily implementation dependent. We don't even guara

Re: [Python-Dev] AST optimizer implemented in Python

Not so fast. If you make this a language feature you force all Python implementations to support an identical AST API. That's a big step. Not that AST manipulation isn't cool -- but I'd like to warn against over-enthusiasm that might backfire on the language (or its community) as a whole. --Guido
