Comment after let binding breaks downstream output

[deviousasti]

Issue created from fantomas-online

Code

let value = // TODO: some comment
    let v = 2 + 3
    v

let k = -1

Error

Fantomas was able to format the code but the result appears to be invalid F# code.
Please open an issue.

Formatted result:

let value = // TODO: some comment
    let v =2 + 3
    v

let k =-1

Problem description

isValidFSharpCode fails if there's a comment after a let binding which doesn't immediately return a value.

Extra information

• The formatted result breaks by code.
• The formatted result gives compiler warnings.
• I or my company would be willing to help fix this.

Hello Asti, many thanks for reporting this.
I'm afraid it is related to the refactoring in #1230.
As it immediately rang a bell, I've added a fix in #1285.
Nonetheless, I appreciate you ticking off the box I or my company would be willing to help fix this..

That was amazing.

I'd just started on the case when you posted.

The tests are passing, so I'm closing it. Thank you very much.
