Bacon's goal is to ease the coder compiler dialectics.
It lets you stay in your editor while having errors, warnings (when there's no error) and test results conveniently displayed without delay (meaning you don't see a flow of useless lines during computation unlike the usual watch based solutions).
Bacon handles resizing, wrapping lines, and generally aims at being usable in a tiny terminal (I most often have on screen at least my editor, bacon, tailed log and a test frame):
As it looks finished to me, I just tagged it 1.0.
