Lightweight syntax for creating JSon objects using Newtonsoft's Json.Net
There's an easy way to create JSon objects using Newtonsoft's Json.Net. The common problem with Json.Net is that there's usualy a lot of overhead when creating Json with it as there're a lot of 'new', parentheses, nested objects when we don't need them. And it becomes annoying quite fast. DU Json and toJson function allow to create Json tree and convert it to Json.Net JObject hierarchy. On the examples the usage of lightweight syntax doesn't give a lot of win but it will be more clearer when it come to more complicated objects.

JsonValue JsonConverter
Not super efficient, and doesn't work on every case, but works most of the time. Json.NET JsonConverter for a JsonValue, i.e. JsonValueConverter. If you're using with a converter for discriminated unions, be sure to give this one higher precedence (since JsonValue is implemented as a DU).

Fast(er) Set creation
Set creation can be quite slow for large sets (> 15000ish string items). If input sequence to create the set is sorted then some optimizations can be applied. For even larger unordered sets (> 30000ish string items) it can be faster doing an up front sort on the data, and then using the Set creation method as described. 1) Set.union is very fast when the greatest element in one of the sets is less than the smallest element in the other; basically becoming an O(1) operation. And Set.add is faster for smaller sets than larger sets, given O(log2 n) of the add operation. So when we have ordered data, makings lots of smaller sets from the stream and union-ing them together can provide a performance boost. 2) On top of the method described in (1), because all the sets are immutable inputs and outputs, then they can be partitioned off onto Tasks to perform the set creation in parallel. If you are using Newtonsoft's Json.net, then provided is a JsonConverter that can be added to the serializer to use this for Set creation like: serializer.Converters.Add Newtonsoft.fastFSharpSetConverter

Finding nearest airplane to a location
Given a location as a float tuple (latitude, longitude) it will return the plane closest nearby as a JsonValue using the OpenSky API. For fun also demonstrating some operator overloading with (-->) between two coordinates. I'm new to these functional languages, so please feel free to update the solution with interesting refactortings and whatnot.
