How can I constrain a function to not accept partially applied functions

I have a serialization function that I feed data into, some times I miss an argument to the data generating function, and as a result I serialize the partially applied function. Json.Net does not throw up about this, but provides a nice empty object {}

I would like to constraint my serialization function to not accept partially applied arguments:

let mySerializer<'a when : 'a isnotafunction> (data:'a) : string = 
    JsonConvert.SerializeObject(data)

So far I have had no luck in finding a way of doing this.

You can check if `'a` is an instantiation of `FSharpFunc<_,_>` – Fyodor Soikin Mar 01 '16 at 14:41
how would I go about making this into a constraint? Ie `'a when : 'a not :> FSharpFunc<_,_>` – Vidar Mar 01 '16 at 14:45
