TEA is reentrant, and I use it at that at my job. The "states" are 
possible to save as I have a "Context" class where all variable data is 
located and these are again "streamable" (or will be, as I don't use 
this feature yet).

But I quess that the state information also need to be stores in the 
glob2 type that one can manipulate from the script (or C++) api.

Ahh, I newer get use to lisp :-) I really like emacs, but I get dizzy 
when I look into there script base :-)

TEA is a clone of differant ideas, syntax is a little like C, variable 
syntax from ML, and I have a special kind of type system and it is 
extreamly typesafe (no indirect conversions at all). My primary 
mutivation to make the language was to be able to evaluate as much of 
the script before starting executing it, as this was a needed feature.

It is work in progress, and I am working at impl. the executer as a 
small stack machine, as the current executer is a bit slow (half speed 
as python). All the language is written in C++ :-)

I quess that this is possible, if I understand you right.

I quessed that. I liked the idea to impl. TEA in glob2 as the language 
will become more mature, and I can get to know this funny game's inner 
working.
