End-of-line comments lost when formatting multiline type function signature

[jrnail23]

Issue created from fantomas-online

Code

namespace Test

module OrderProcessing =
  type ValidateOrder =
    CheckProductCodeExists    // dependency
      -> CheckAddressExists   // dependency
      -> UnvalidatedOrder     // input
      -> Result<ValidatedOrder,ValidationError>  // output (Result b/c one of deps returns a Result)

Result

namespace Test

module OrderProcessing =
    type ValidateOrder = CheckProductCodeExists -> CheckAddressExists -> UnvalidatedOrder -> Result<ValidatedOrder, ValidationError> // output (Result b/c one of deps returns a Result)

Problem description

There are a couple of things going on here -- there's the issue of losing all but the last comment, and there's also the issue of this function signature being forced onto one line. My max line width is set to 80, and the result's width is 164 -- this signature should be broken up over multiple lines. Even without the comments, Result<ValidatedOrder, ValidationError> begins at column 73, but ends at column 112

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.
