Not to ruin the joke, but you could do that already. Nasal has always
been a fully functional language, with recursion, lexical closures and
anonymous lambda expressions. :)
This feature allows for calling Nasal scripts (not functions)
recursively. That is, have a command binding that is a Nasal script,
that then calls another FGCommand object that is implemented in
Nasal. Before, this wasn't possible because there was only one
execution context for the scripting engine. Now you can have lots.
So you can, for example, stash one away on a timer while another one
runs. This allows for pseudo-multithreading of many scripts at once,
which run forever in loops like:
while(1) {
if(NeedToUpdate()) { DoSomethingUseful(); }
sleep(0.2);
}
This kind of programming can be simpler than running from a timer.
Although the context is fairly heavy-weight compared with a timer
entry, so we don't want thousands of them sitting around.
