hi,
just in case folks didn't know, the inventor of flow-based programming
loves lua enough to have started off on an implementation using it.

Thanks for the head up, yet another thing I thought I had invented all
by myself :)
In case anyone is interested in this sort of things, I remind of l-flow,
a toy flow programming language written in pure Lua:
https://github.com/xopxe/lflow
A sample program could be as follows:
-----------------------------
'gris:1', 0.1 > sensor_poll > sense_left
'gris:2', 0.1 > sensor_poll > sense_right
sense_left, '>', 50 > threshold > forward_left
sense_right, '>', 50 > threshold > forward_right
forward_left, forward_left > motors >
-----------------------------
This controls a line-following robot, a typical first step in
educational robotics (variations are a "moth", follow the light and
"roach", escape from light).
The motivation behind it is pretty specific:
1. Test Lumen, the multitasking scheduler (https://github.com/xopxe/Lumen)
2. Experiment with an environment for building simple control programs
for educational robotics: is it possible learn to write control
applications for robots without learning imperative programming before?
But this could inspire someone to do something, so there it goes.
Jorge.
