Could you elaborate on that? What's your definition of moderately complex?
I've got (what I think is) a small dialplan in AEL now, but I'm looking into pbx_lua which seems nicer at least.

About 5000 lines of code.

It's hard to find anything that's worse than AEL, actually :)

I liked a lot of things about lua, but walked away when I realised it had "os.getenv()" but not "os.putenv()".
I don't know how frugal they want to be but that was a tad too frugal for me.

A whole bunch of OSes don't have a C-layer putenv() that a Lua putenv could be implemented in terms of, including even recentish Solaris releases. Not having it is hardly an indictment.

Actually, saying "too frugal for me" is hardly an "indictment" :-)

What's really annoying to me is another piece of frugality: no regex library, but instead a *new* domain-specific regex-like language with less power and gratuitously different syntax, just because the implementation is a bit smaller (not even very much smaller than some modern regex implementations). Sure, a regex module is available, but other packages will generally prefer to use 'patterns' instead, because they're built in.
