Totally, this is important stuff. I suggest we follow Mike wherever he
goes and collect all his pieces of concrete advice.
But the wiki is good for initial collaboration.
I've done a template-ized version of Francesco's code, and it's full
of beauties like:
$(AL 's.y') = $(VL 'v_')
which expands to
s.y[0],s.y[1] = v_0,y_1
(The search for the ultimate syntax continues...)
Initially my Lua ears were tingling and then I realized - of course,
these C arrays are zero-based!
