That is indeed rather interesting.

The curve construction reminds me of a feature (or set of features)
from MetaPost that I believe is not available in PyX, but which can be
quite nice... Basically, it's the spline stuff that tries to fit a
curve to the points you give (without you having to give the Bezier
contour points explicitly). Also, you can give such (very useful)
constraints as the direction of the curve at a given point, and the
spline will adapt to that. I assume this could quite easily be built
on *top* of PyX -- I just thought it might be nice to have it as an
integrated part of the path mechanism? (I don't know the details of
the splines used by MP/MF, but they look fine, IMO.)

And another thing... I have no idea how it's done in MP (in MF I can
sort of understand it) but MP allows you to use custom-made paths as
brushes in other parhts. Very nice for calligraphic-like looks, for
example. (I guess one heavy-handed way of doing it would be simply to
replicate the brush all along the path, with the appropriate spacing
calcilated somehow, perhaps even dynamically along the path.)

Sorry to turn yet another thread into one about possible features...
These are just a couple of things that came up when I took a stab at
implementing big, flexible braces (such as these:
http://just.letterror.com/ltrwiki/GlyphInterchangeFormat) in PyX.
