Description: Multiple Dispatch
        =================

        A relatively sane approach to multiple dispatch in Python.
        
        This implementation of multiple dispatch is efficient, mostly complete,
        performs static analysis to avoid conflicts, and provides optional namespace
        support.  It looks good too.
        
        See the documentation at https://multiple-dispatch.readthedocs.io/
        
        
        Example
        -------
        
        .. code-block:: python
        
           >>> from multipledispatch import dispatch
        
           >>> @dispatch(int, int)
           ... def add(x, y):
           ...     return x + y
        
           >>> @dispatch(object, object)
           ... def add(x, y):
           ...     return "%s + %s" % (x, y)
        
           >>> add(1, 2)
           3
        
           >>> add(1, 'hello')
           '1 + hello'
        
        What this does
        --------------
        
        -  Dispatches on all non-keyword arguments
        
        -  Supports inheritance
        
        -  Supports instance methods
        
        -  Supports union types, e.g. ``(int, float)``
        
        -  Supports builtin abstract classes, e.g. ``Iterator, Number, ...``
        
        -  Caches for fast repeated lookup
        
        -  Identifies possible ambiguities at function definition time
        
        -  Provides hints to resolve ambiguities when they occur
        
        -  Supports namespaces with optional keyword arguments
        
        -  Supports variadic dispatch
        
        What this doesn't do
        --------------------
        
        -  Diagonal dispatch
        
        .. code-block:: python
        
           a = arbitrary_type()
           @dispatch(a, a)
           def are_same_type(x, y):
               return True
        
        -  Efficient update: The addition of a new signature requires a full resolve of
           the whole function.  This becomes troublesome after you get to a few hundred
           type signatures.
        
        
        Installation and Dependencies
        -----------------------------
        
        ``multipledispatch`` is on the Python Package Index (PyPI):
        
        ::
        
            pip install multipledispatch
        
        or
        
        ::
        
            easy_install multipledispatch
        
        
        ``multipledispatch`` supports Python 2.6+ and Python 3.2+ with a common
        codebase.  It is pure Python and requires only the small `six
        <https://pypi.org/project/six/>`_ library as a dependency.
        
        It is, in short, a light weight dependency.
