placeholder 0.3.1

Operator overloading for fast anonymous functions.

Latest Version: 0.4

A placeholder object uses operator overloading to create partially bound functions on-the-fly. When used in a binary expression, it will return a callable object with the other argument bound. It's useful for replacing lambda when doing functional programming. For example:

• __[key] == operator.itemgetter(key)
• __.name == operator.attrgetter('name')
• (1 + __) == (1).__add__ or partial(operator.add, 1)
• (__ - 1) == (1).__rsub__ or lambda obj: obj - 1

where '__' is a placeholder instance (it can have any name of course).

See tests for more example usage. Supported on Python 2.5 or higher, including Python 3.x.
