Start of work on a new input model. The current one uses
|
|
`s:evaluate`, which works, but burns through the temporary
|
|
strings pool. For this to be practical, I need to avoid doing
|
|
that, so it's time to write a replacement.

Things needed:
|
|
|
|
- termios device & words (or add termios to unix device?)
|
|
- colors for interface elements
|
|
- write a better alternative to `s:evaluate` to avoid consuming
|
|
the temporary string space
|
|
- refactor & document everything
|
