Hi,
As you know, I've been playing with Lua for some time now, and my
attempt to write a Lua compiler targetting Parrot has not been
completely unsuccessful, but it was quite some work.
Anyway, at some point I realized that PIR looks very much like Lua
bytecodes (which I had inspected at that time already). So, I thought it
may be a nice project to write a Lua2PIR translator, which takes a
binary Lua file (compiled with the Lua compiler, so you'll need to get
Lua (to be found at www.lua.org))
If you are interested, it can be found at

It works pretty good. It needs still many tests, in order to check if
all special cases are covered, but quite complex examples do work
already. Furthermore, the Lua PMCs have to be integrated, as it just
uses the Parrot basic types (Float, String, Hash, etc). It's also nice
to see what kind of code the Lua compiler should more or less be generating.
Kind regards,
Klaas-Jan Stol
