'with' incorrectly removed

[pviotti]

Issue created from fantomas-ui

The keyword 'with' gets incorrectly removed.
Similarly to what pointed out in #388, which for some reason has been closed: has this been fixed? If so, could you advice on which version contains the fix? Thanks in advance.

Code

type MyType = En | It | Fr with
    override this.ToString() = toString this
    static member fromString s = fromString<MyType> s

Error

type MyType = | En | It | Fr
    override this.ToString() = toString this
    static member fromString s = fromString<MyType> s

Options

Fantomas 2.9.2

I think fantomas will never print out the with keyword as it can be left out.
We could tackle this in the trivia branch to preserve the with keyword.

Yes it is fixed in 3.0 (trivia) version.

I think removing with when it is not needed is OK.

Nothing against removing something that is useless, but, to be clear, the with in the example above should stay, otherwise it does not compile, saying error FS0010: Unexpected keyword 'override' in definition. Expected incomplete structured construct at or before this point or other token., using donet version: 2.2.108 and fsharpc version 10.2.3 for F# 4.5.

otherwise it does not compile

That's true for current version (2.9.2).

In newest version (3.0) it is formatted as

type MyType =
    | En
    | It
    | Fr
    override this.ToString() = toString this
    static member fromString s = fromString<MyType> s

which is correct. So, this issue is already fixed, just not released in stable.
