Composing a list of functions
Composition of functions in F# is easily achieved by using the >> operator. You can also chain an arbitary amount of functions (represented as a list or sequence) together by folding the list/seq with >>. [More formally: the set of endomorphisms 'a -> 'a forms a monoid with the binary, associative operator ">>" (or "<<") and the neutral element "id".]

Implementing active objects with a MailboxProcessor
Mailbox processors can easily be used to implement active objects. This example shows how to do that with a reusable wrapper type and minimal boilerplate code in the actual class definitions. Supports both asynchronous calls and synchronous calls. For the latter case, exceptions are automatically propagated back to the caller.
