Multiple List concat operators are not seen as the same operator.

Issue created from fantomas-online

Code

        let allDecls = inheritsL @ iimplsLs @ ctorLs @ instanceValLs @ methLs @ ilFieldsL @ propLs @ eventLs @ staticValLs @ nestedTypeLs

        let allDecls = inheritsL + iimplsLs + ctorLs + instanceValLs + methLs + ilFieldsL + propLs + eventLs + staticValLs + nestedTypeLs

Result

let allDecls =
    inheritsL
    @ iimplsLs
      @ ctorLs
        @ instanceValLs
          @ methLs @ ilFieldsL @ propLs @ eventLs @ staticValLs @ nestedTypeLs

let allDecls =
    inheritsL
    + iimplsLs
    + ctorLs
    + instanceValLs
    + methLs
    + ilFieldsL
    + propLs
    + eventLs
    + staticValLs
    + nestedTypeLs

Problem description

Fantomas has heurstic that if the operators are all the same in a large nested infix application, it will place them all on a new line. For some reason, this isn't working for @.

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.
