| In my opinion, YES -- it's worth seriously considering it. A single,

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 $

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 :)
