Disposable Scopes provided by scope {...} computational workflow.
This snippet provides a builder for scope {...} computational workflow that returns a Scope object implementing System.IDisposable interface. All "use" bindings inside scope {...} workflow are kept from being disposed immediately when computation leaves scope. Instead, they are disposed only when resulting Scope object is disposed. This makes possible to access disposable outside the scope while it remains usable. This can be achieved by via return statement of workflow that can return, for example, a closure that encapsulates disposable. scope {...} return value is available through Value property of Scope object. Scopes may be nested through let! binding that means that nested scope will be disposed when the resulting scope is disposed.

Rotate or shift lists
This rotates or shifts a list. Unlike http://www.fssnip.net/qY/title/Rotate-List, which runs exponentially, this runs at O(n). In case of overflow (i.e., shift index is larger than the size of the list) will run at most once more with the modulo. This is done to prevent using `List.length` prior to entering the function, as that would lead to a perf punishment of an extra O(n) on each invocation. For large lists, `shift largeList 1` would then get a big performance hit.

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.

The Haskell const function
The const function is simple, but you can use it to make your code more legible. In this example we convert a unary function to a function of arity 2 (that ignores the second argument). Also by using the flip function from Haskell (which is equally easy to define) you can ignore the first argument.

Partition a sequence until a predicate is satiated
This function is given a partition predicate and a sequence. Until the predicate returns false, a list will be filled with elements. When it is, both the list and the remainder of the sequence will be returned. Note that this example preserves the laziness of the unchecked sequence elements.

Asynchronous sequences
An asynchronous sequence is similar to the seq
109 people like thistype, 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.
