Hello,
With the latest version and the following test-file "test.cld":
--8<---------------cut here---------------start------------->8---
local t = {}
package.seeall(t)
setfenv(0, t)
context.starttext()
context"bla"
context.stoptext()
--8<---------------cut here---------------end--------------->8---
I get this error:
PANIC: unprotected error in call to Lua API (attempt to index a nil value)

I want to prevent pollution of the global environment, when I need to
define my own globals. But of course, I can do that with a name-space
prefix, that's what I'm doing now.
I've just posted the error, because perhaps it reveals a bug somewhere.

in lua 5.2 the environment related mechanism will change a bit anyway so
best not depend on that now
