  ):
      """Dispatch function on the types of the inputs
  
      Supports dispatch on all non-keyword arguments.
  
      Collects implementations based on the function name.  Ignores namespaces.
  
      If ambiguous type signatures occur a warning is raised when the function is
      defined suggesting the additional method to break the ambiguity.
  
      Examples
      --------
  
      >>> from sympy.multipledispatch import dispatch
      >>> @dispatch(int)
      ... def f(x):
      ...     return x + 1
  
      >>> @dispatch(float)
      ... def f(x): # noqa: F811
      ...     return x - 1
  
      >>> f(3)
      4
      >>> f(3.0)
      2.0
  
      Specify an isolated namespace with the namespace keyword argument
  
      >>> my_namespace = dict()
      >>> @dispatch(int, namespace=my_namespace)
      ... def foo(x):
      ...     return x + 1
  
      Dispatch on instance methods within classes
  
      >>> class MyClass(object):
      ...     @dispatch(list)
      ...     def __init__(self, data):
      ...         self.data = data
      ...     @dispatch(int)
      ...     def __init__(self, datum): # noqa: F811
      ...         self.data = [datum]
