SpaceBeforeUppercaseInvocation applied in the middle of a invocation chain

[Bobface]

Issue created from fantomas-online

Notice the space between a.Some.Thing and ("aaa").[0]. That space makes it a different expression, namely ("aaa").[0] is interpreted as parameter to a.Some.Thing.

Code

module SomeModule =
    let DoSomething (a:SomeType) =
        let someValue = a.Some.Thing("aaa").[0]
        someValue

Result

module SomeModule =
    let DoSomething (a: SomeType) =
        let someValue = a.Some.Thing ("aaa").[0]
        someValue

@Bobface not sure I understand; this leads to a compiler error or...?

[Bobface]

@knocte Yes. The original is interpreted as (with extra parenthesis):

let someValue = (a.Some.Thing("aaa")).[0]

The formatted is interpreted as (with extra parenthesis):

let someValue = (a.Some.Thing)(("aaa").[0])

[Bobface]

Note: Knocte and I have agreed to fix this on our side by applying parenthesis like this:

let someValue = (a.Some.Thing "aaa").[0]

[knocte]

Yes, otherwise fixing this would break the purpose of SpaceBeforeUppercaseInvocation setting.

I feel like we should still fix this at Fantomas side as well.
Take this example.

We don't add the space in the first line to indeed not break the code.
This feels like a variant of that.
