Convert lambdas assigned directly to names to functions.

[Lattyware]

I did a few searches and couldn't find any previous discussion of this—apologies if I missed something.

I think it would be a good feature to rewrite lambdas assigned directly to names into normal function definitions.

E.g:

let
    a =
        (\b -> 1)
in
...

To:

let
    a b =
        1
in
...

I commonly find myself refactoring out lambdas from inline to names, and forgetting to make this change, which feels like it is always the preferable way to do this.

Something similar I see a fair bit is:

(\b -> someFunction b)

which could be replaced with

someFunction

I guess I'd wonder if this is likely to be an intermediate state for code that the developer might want to save without a reformat, so they can then make further changes to it.

Maybe this sort of changes is more suitable for elm-analyzer which would give users the choice
