is it possible to rename a field in a ParamObject?

[joprice]

With a param object like https://fable.io/docs/javascript/features.html#paramobject, is it possible to bind a field to a different name in the js? I tried using CompiledName and Emit, but I don't think these attributes are being used for determining the object's fields.

No the name of the field is based on the name of the variable.

What is the use case for renaming the field ?

So far, it's just a curiosity as I'm prototyping but I want to use alternate names for keywords like class without having to escape the identifier with backticks, so className instead of ``class``, but I can imagine other cases where the internal and external names differ. Perhaps Emit could be used on the constructor arg? Modifying the example from the docs:

module ParamObject =
      [<AllowNullLiteral>]
      [<Global>]
      type Options [<ParamObject; Emit("$0")>] (
           [<Emit("class")>]
           className: string, ?isCaseSensitive: bool) =
        member val className: string = jsNative with get, set
   ...

The main goal for ParamObject is to offers a binding to a JavaScript library, for this reason I believe it is best to stay close to the original names used in the library so people don't get too confused and can easily translate the code.
