Fantomas removes the 'and' if there are multiple member constraints on a function declaration

[JackMatusiewicz]

Issue created from fantomas-online

When a function has multiple member constraints, fantomas will remove the 'and' leading to invalid F# code

Code

namespace Blah

module Foo =
    val inline sum : ('a -> ^value) -> 'a Foo -> ^value
        when ^value : (static member (+) : ^value * ^value -> ^value) and ^value : (static member Zero : ^value)

Error

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

Formatted result:

namespace Blah

module Foo =
    val inline sum: ('a -> ^value) -> 'a Foo -> ^value when ^value: (static member (+): ^value * ^value -> ^value) ^value: (static member Zero: ^value)
