Haskell on Pebble smartwatch

Hi, while I’m waiting on my pebble, I’m contemplating to try writing something (watchface with extras) in Haskell (using microhs?) for it. Does anyone have pointers to previous similar efforts? I’m not even sure how sensible or hard this would be, as a smartwatch is tightly constrained and most of the time it should be just waiting for external events. Tldr: smartwatch Haskell - any pointers are welcome.
