A little off-topic, but there is a CallASWI module that allows versions of
RISC OS back to 3.1 to use OS_CallASWI. It's only about 500 bytes long.

More on-topic-ly, I'm writing an LTN about interfacing Lua to other
languages, based on my experience with OPL. (Since I was the person who
complained about the lack of LTNs in the first place, this seemed only
fair!)
