(* F# lacks proper support for higher-kinded abstraction such as ML
functors or Haskell typeclasses. In particular it makes it seemingly 
impossible to define functions that work for every type constructor.
The code below demonstrates that this functionality can be partially
recovered by using inline functions with static member constraints.
The approach requires explicitly passing typeclass instance values.
Error messages and derived types are horrible. Nonetheless, there is
some type safety - if the typeclass instances have been defined right,
type-unsafe code will be rejected by the typechecker, albeit with a
hairy message. Another disadvantage is the need to invent operators. *)

Just found out that VB.NET can infer function types correctly. I.e. this won't work in C#:

var withMemoryStream =
    (Action<MemoryStream> f) => () => {
        using (var ms = new MemoryStream())
            f(ms);
    };

("Cannot assign lambda expression to implicitly-typed local variable", because it can't tell a Func<T> from an Expression<Func<T>>). 
But the exact same code in VB.NET does work:

var parser = document.createElement('a');
parser.href = "http://example.com:3000/pathname/?search=test#hash";

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"
