Both of these were abstracted out of a more complex binding library, so
I haven't actually tried them. I'll try to post the real code (which
actually works, I think) later today.
Sorry, that was my mistake.
After reading all this I am still confused about what the environment
table in a userdata does. Is it just a place to store a table that can
be retrieved and manipulated, or does it actually come to play in some
API calls somewhere? As I mentioned, I don't see it being used
anywhere in the 5.1 API. Sorry about being dense, but I really think
this will solve a lot of problems for me, so I really want to
understand it well.
Me, too. :)
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.
