Unlike Scheme where exactness is implemented as taints, the Python implementation associated exactness with data types. This created inheritance issues (making an exact subclass of floats would result in the subclass having both an explicit Exact registration and an inherited Inexact registration). This was a problem for the decimal module which was designed to span both exact and inexact arithmetic. There was also a question of use cases and no examples were found where ABCs for exactness could be used to improve code. One other issue was having separate tags for both the affirmative and negative cases. This is at odds with the approach taken elsewhere in the Python (i.e. we don't have an ABC both Hashable and Unhashable). ........ r61405 | raymond.hettinger | 2008-03-15 21:37:50 +0100 (Sat, 15 Mar 2008) | 1 line Zap one more use of Exact/Inexact. ........ r61406 | neal.norwitz | 2008-03-15 23:03:18 +0100 (Sat, 15 Mar 2008) | 9 lines Add a warning for code like: assert (0, 'message') An empty tuple does not create a warning.

This has been discussed at http://bugs.python.org/issue1682. It's useful primarily for teaching, but it also demonstrates how to implement a member of the numeric tower, including fallbacks for mixed-mode arithmetic. I expect to write a couple more patches in this area: * Rational.from_decimal() * Rational.trim/approximate() (maybe with different names) * Maybe remove the parentheses from Rational.__str__() * Maybe rename one of the Rational classes * Maybe make Rational('3/2') work. ........ r59978 | andrew.kuchling | 2008-01-15 06:38:05 -0800 (Tue, 15 Jan 2008) | 8 lines Restore description of sys.dont_write_bytecode. The duplication is intentional -- this paragraph is in a section describing additions to the sys module, and there's a later section that mentions the switch. I think most people scan the what's-new and don't read it in detail, so a bit of duplication is OK. ........ r59984 | guido.van.rossum | 2008-01-15 09:59:29 -0800 (Tue, 15 Jan 2008) | 3 lines Issue #1786 (by myself): pdb should use its own stdin/stdout around an exec call and when creating a recursive instance. ........
