Not currently. Adding it would actually be non-trivial, because (as
in most similar languages) "loading" and "running" a script are the
same thing. Being able to load a script from Nasal code is equivalent
to running a recursive Nasal interpreter context, something that the
current implemention doesn't support.

So, if I really wanted to execute a script, I would really have to first nil'ing all existing nasal modules as well as the scripts from the property lists, in order to re-load then all of it INCLUDING the new file ?

I suppose we could wire up an fgCommand that did a script load, which
would work fine so long as you called it from a non-nasal context
(keyboard binding, etc...).

yes, actually I was not even (yet) thinking of loading one script from another one, rather I would like to have a way to load a particular script on demand, using a fgCommand linked to the menubar for that purpose would definitely be already sufficient.

Fixing the interpreter to allow multiple contexts is definitely worth
doing.  This would also allow for a non-callback API, where a script
could "sleep" for a bunch of frames and be woken up later on.

This sounds at lot like the solution to a problem that I just mentioned: the event loop issue, so how are callbacks currently handled in Nasal ?
