Thanks,
Patrick. Yes, that's very helpfu. I found the talk: http://lambda-the-ultimate.org/node/3894
He says about 4 minutes in that lua is not good for numerical
computation, which gives me pause. (I'm checking out numlua.)
He mentions the banking application about 16m51s in. Is this
thread talking about the same application? http://mail.python.org/pipermail/pypy-dev/2007-February/003558.html
("I'm currently building a distributing financial
trading application that allows users to write trading
models in python and lua. I had to introduce lua,
since there is no way to completely "secure" user
models written in cPython.")

Hi Holly
I think this video is great, it brings up some topics.
One, I hope you will agree that Roberto is very bright and handles
difficult people well(I don't). If you are considering Lua, there is
an awesome community behind it, right from helpful newbies to the
design team itself. However it's so great that I have spent most of
the last two years trying to code everything in Lua, this was a
mistake.
Two, Roberto discussed the myth of the general purpose programming
language in the video. Lua isn't perfect for every application.
Library support is patchy and changing this is not a priority for
the design team. Lua really shines if you need to embedded it where
feature rich/fat pig languages like Python, PHP and Ruby won't fit.
It's good for embedding and extending, use caution outside of this.
As Ezequiel had mentioned, you could write code to handle numeric
computations in C and then call it from Lua. You can also do this
with Fortran too.
