Lua on an embedded ARM with 128K ROM and 16K RAM

[Tim Eccles <tim@...>]

I have a little embedded robot-style system where the control program 
does simple stuff like "turn left if sensor_1 and sensor_2." The micro 
is an ARM with 128K of flash ROM and 16 of RAM, almost all free.

I would like to be able to send the control program as a Lua script - 
the most friendly solution. So the question is whether a useful amount 
of Lua could be shoehorned into the ROM/RAM.

I would guess that a reasonable subset of the language will fit into 
128K, but would the 16K RAM limit be an insoluble problem?
