looks good. i particularly like that a single "-O#" sets things nicely both for translation and the target. > We have a number of open branches; does it make sense, in an effort to > reduce confusion, to apply this change to some of them too? Maybe, yes. Reminds me: I'd really like to see better tool support for working with branches. eazysvn from Marius Gedminas might help a bit (haven't tried) but i am rather thinking of something that helps me efficiently managing e.g. my "codespeak.net/svn/pypy" checkout, including quick overviews of active branches, easy merging (without knowing numbers) etc. Some might think "dvcs!" here but it's a while until we go there, i think, and i even consider somewhat orthogonal to having support for my particular work flow. cheers, holger _______________________________________________ [email protected] http://codespeak.net/mailman/listinfo/pypy-dev
