Question: fable compatible?

[OnurGumus]

Is this at least partially fable compatible?

[farlee2121]

Hmm. I haven't tried using it with fable yet. Looking at the compatability guide. I would guess it is not very compatible because

It's not possible to type test against interfaces or generic types.

The core FsSpec library only depends on Fsharp.Core and a few basic types from the BCL (IComparable<T>, IEnumerable, EqualityComparer<T>). The problem comes from the use of type tests and reflection to check implementation of those interfaces.

[farlee2121]

Hmm, actually most of the type testing is in the data generation library.
I think validation (thus explanation and formatting) might work for all the constraints except length.
We might be able to change the implementation of length validation to accommodate Fable too

[OnurGumus]

Yes tests don't have to be fable compatible.

[farlee2121]

Not tests as in automated tests but type tests as in this example

These are part of the production code and are not supported by fable
