Binding is the act of tying together a function to some arguments for deferred (lazy) evaluation. Named Lazy functions require a bit of typing. Unlike (unnamed) lambda expressions, we need to write a functor somewhere offline, detached from the call site. If you wish to transform a plain function, member function or member variable to a lambda expression, bind is your friend.

	Note
	Take note that binders are monomorphic. Rather than binding functions, the preferred way is to write true generic and polymorphic lazy-functions. However, since most of the time we are dealing with adaptation of existing code, binders get the job done faster.

There is a set of overloaded bind template functions. Each bind(x) function generates a suitable binder object, a composite.
