I dunno, I do prefer having type directed editing (eg. auto case splitting, and autocomplete), so full type inference is less of a holy grail to me.

Damas-Hindley-Milner inference is also hyper-optimised to a specific point on the design space, and does an excellent job there, but (to echo Conor McBride) I would love to see less conflation of the ideas of execution phase, parametericity, and implicitness going forward.
