Lua is an easy language to embedded in resource limited micros.
The Programming Language Lua
eLua - eluaproject
In the past I set up a project where non-computer people were writing simple scripts to handle sensor scaling.
The customer always changed the sensors in the field and there was no way to know in advance how to scale data.
They didn't even realize they where using a computer language to get the job done.
Squirrel - The Programming Language
is a combination of Python and Lua. Core code takes about 8K of C.
I have not yet personally used it so, don't know how easy it is to embedded in a small micro.
There is also CPython - Wikipedia, the free encyclopedia , that you probably already know about.
