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.

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".]
