Sorry, that was my mistake.

Hmmm. Are you saying that you don't know why userdatas have an 
environment? (it would me feel better if so :-)

I thought I would understand it better if I read the VM doc to see what 
the various GET and SET opcodes did. But in looking at the code for 
these in lvm.c it still looks like the only environment that ever gets 
used is the one in the currently running function.
