Is it possible to have hard real-time with lexical scope?

Adding to your digession, before writing my own micro-lisp, I would try to find or port lua for the embedded system in question. It is very small and offers much of LISP: first-class functions, closures, no continuations but co-routines.

Lua is small

Adding Lua to an application does not bloat it. The tarball for Lua 5.1.4, which contains source code, documentation, and examples, takes 212K compressed and 860K uncompressed. The source contains around 17000 lines of C. Under Linux, the Lua interpreter built with all standard Lua libraries takes 153K and the Lua library takes 203K.

Lua is free

Lua is free open-source software, distributed under a very liberal license (the well-known MIT license). It may be used for any purpose, including commercial purposes, at absolutely no cost. Just download it and use it.
