The idea would be to deprecate fromMaybe for 7.12 and remove it completely later.
I would deprecate it, but not remove it. Otherwise people will think that this obvious function is missing by accident. We would then encounter various discussions about adding it in the close future.
that’s a more useful idea, but again: Why fromJust and not head etc.? If you would continue this thought of line towards some consistency, then we’d need a way to annotate partial functions in general, and have a dedicated flag -fwarn-partial-functions. (It would behave just like deprecations – but reported separately.). This would go well with -fwarn-incomplete-patterns. Such a thing might be useful.
