Currying issue

[JaggerJo]

Description

When calling curried functions from other projects the functions get un-curried. This leads to the following exception:

TypeError: Cannot read properties of undefined (reading '0')

Repro

Create a fsharp library that includes the following code:

namespace Repro

#if FABLE_COMPILER
open Thoth.Json
#else
open Thoth.Json.Net
#endif

type Person = {
    First: string
    Last: string
}

[<AutoOpen>]
module PersonExtensions =

    [<RequireQualifiedAccess>]
    module Person =

        let decode =
            Decode.object(fun get ->
                let epoch = get.Required.Field "first" Decode.string
                let timezoneId = get.Required.Field "last" Decode.string
                { Person.First = epoch; Person.Last = timezoneId }
            )

    type Person with

        static member Decode (path: string) (value: JsonValue) =
            Person.decode path value

Add a reference to Thoth.Json (Version="5.1.0")

Call the decode function in a project referencing the library.

module Test = 

#else
    open Thoth.Json.Net
    open Expecto
#endif

    open Repro

    let test () =
        let json =
            """
            {
                "first": "John",
                "last": "Doe"
            }
            """

        let person: Person = Decode.unsafeFromString Person.decode json
        ()

Calling test fails as the decode function is un-curried by the compiler.

TypeError: Cannot read properties of undefined (reading '0')
