A quick-and-dirty editor for discriminated unions in a property grid. I use this for editing trees of F# records and unions. Note that any records must have a "Default" static property which returns a default instance.

Here I give an example of a data structure known as a skew binary list and also an example of how to use the cons pattern, normally reserved for FSharp lists, in your own union cases. It is not possible to do the same with the nil union case, . Nor is it possible to use any other symbols (as far as I know). This kind of sucks.
