[Working on the J2 patch]... If we use a keyword, we need a __future__ and AFAICT a new CO_FUTURE_DECORATORS flag. Should it just be 0x4000? #define CO_NOFREE 0x0040 /* XXX Temporary hack. Until generators are a permanent part of the language, we need a way for a code object to record that generators were *possible* when it was compiled. This is so code dynamically compiled *by* a code object knows whether to allow yield stmts. In effect, this passes on the "from __future__ import generators" state in effect when the code block was compiled. */ #define CO_GENERATOR_ALLOWED 0x1000 /* no longer used in an essential way */ #define CO_FUTURE_DIVISION 0x2000 #define CO_FUTURE_DECORATORS 0x4000 I'm mostly wondering why there's a big gap between CO_NOFREE and CO_GENERATOR_ALLOWED. Or is it a non-issue, pick-what-you-want? Robert Brewer MIS Amor Ministries fumanchu@amor.org
