I see in 5.1-work6 that you can now set environments not only on both 
C and Lua functions, but also on userdatas. But I don't see anywhere

this environment?
I figured the easiest way to answer this question (for myself) was to 
write a binding library using the feature. I'm generally happy with the 
results, but it makes me wonder about the semantics of userdata 
environments.
Instead of dumping several pages of rumination into the mailing list, 
I've put it all on the Wiki at
