You know what would happen. Math is ubiquitous in lots of code, so syntactic shortcuts would be introduced. Thus, we wouldn't use `a >>= (\x -> 2x) >>= (\x -> x^2)`, but would soon introduce syntactic sugar. For example, we could re-define `[asterisk]` so that it had type `Maybe Number -> Maybe Number -> Maybe Number`. You'd need a `return` (or `Just`) at the beginning, but soon that would be elided too, so that numeric literals would be auto-promoted to `Maybe Number`s. Then the language would add silent mechanisms to allow `Maybe Number`s to be displayed easily. You should check if your `Maybe Number`s are `Just Number`s before letting them out to play, but, if the language doesn't force you, then you know you won't. And then we're right back in the current situation.
