  • Asynchronous sequences

    An asynchronous sequence is similar to the seq type, but the elements of the sequence are generated asynchronously without blocking the caller as in Async. This snippet declares asynchronous sequence and uses it to compare two files in 1k blocks.

  • 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.

  • Active pattern for let binding inside patterns

    The Let active pattern demonstrated by this snippet can be used to assign values to symbols in pattern matching. This is useful for writing complex pattern matching using match as we can handle multiple cases using a single clause.

  • Dynamic operator using Reflection

    Demonstrates how to implement the dynamic operator (?) using .NET Reflection. The implementation supports calling constructors, propreties and methods using simple overload resolution (based on parameter count). It handles instance as well as static members.
