hey folks,

I managed to lose a few days worth of python-dev mail so I'm late to this discussion, but I thought I'd toss in a few (possibly outlying) data points form the visual effects/3d animation world.

here at ILM we use python as the expression langauge in a number of 3d applications, and we usually end up adding a front-end parser so users can reference variable values inline via $ sytanx. they're still essentially writing python code, but with the extra added suger of $ references.

I have first-hand information that the engineers at Pixar chose tcl over python a few years back as the expression language in their commercial shader editor "slim" for exactly this reason as well (i.e tcl already had $ refs, and they didn't want to present their own python-but-not language like we do here).

so if replacing '' % () formatting with $ refs is an option in py3k, allow me to offer a +1000 vote for that :)
