If then expression inside object instantiation breaks when formatted

[LiteracyFanatic]

Issue created from fantomas-online

Code

type Chapter() =
    member val Title: string option = Unchecked.defaultof<_> with get, set
    member val Url: string = Unchecked.defaultof<_> with get, set

let c =
    Chapter(
        Title =
            if true then
                Some ""
            else
                None
            ,
        Url = ""
    )

Result

type Chapter() =
    member val Title: string option = Unchecked.defaultof<_> with get, set
    member val Url: string = Unchecked.defaultof<_> with get, set

let c = Chapter(Title = if true then Some "" else None, Url = "")

Problem description

After formatting, this code no longer compiles. I think the issue is ambiguity with creating a tuple when the comma is on the same line as the if expression. Inserting a newline or wrapping the if expression in parenthesis fixes the compilation error.

Extra information

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

_{Did you know that you can ignore files when formatting from fantomas-tool or the FAKE targets by using a .fantomasignore file?}

Hello,

Thank you for reporting this issue.
We seem to be adding parentheses to the if when the arguments are not named.
sample

Perhaps the this logic can be extended to also take named arguments into account.

Are you interested in submitting a PR for this?
