    to : function
    Coercion function to call on inputs.
    **to_kwargs
    Additional keywords to forward to every call to ``to``.
    Examples
    >>> @preprocess(x=coerce(float, int), y=coerce(float, int))
    ... def floordiff(x, y):
    ...     return x - y
    >>> floordiff(3.2, 2.5)
    1
    >>> @preprocess(x=coerce(str, int, base=2), y=coerce(str, int, base=2))
    ... def add_binary_strings(x, y):
    ...     return bin(x + y)[2:]
    >>> add_binary_strings(\'101\', \'001\')
