# Decorator for creating other decorators. This decorator and the
# wrappers which they use are designed to properly preserve any name
# attributes, function signatures etc, in addition to the wrappers
# themselves acting like a transparent proxy for the original wrapped
# function so the wrapper is effectively indistinguishable from the
# original wrapped function.

def decorator(wrapper=None, enabled=None, adapter=None, proxy=FunctionWrapper):
    # The decorator should be supplied with a single positional argument
    # which is the wrapper function to be used to implement the
    # decorator. This may be preceded by a step whereby the keyword
    # arguments are supplied to customise the behaviour of the
    # decorator. The 'adapter' argument is used to optionally denote a
    # separate function which is notionally used by an adapter
    # decorator. In that case parts of the function '__code__' and
    # '__defaults__' attributes are used from the adapter function
    # rather than those of the wrapped function. This allows for the
    # argument specification from inspect.getfullargspec() and similar
    # functions to be overridden with a prototype for a different
    # function than what was wrapped. The 'enabled' argument provides a
    # way to enable/disable the use of the decorator. If the type of
    # 'enabled' is a boolean, then it is evaluated immediately and the
    # wrapper not even applied if it is False. If not a boolean, it will
    # be evaluated when the wrapper is called for an unbound wrapper,
    # and when binding occurs for a bound wrapper. When being evaluated,
    # if 'enabled' is callable it will be called to obtain the value to
    # be checked. If False, the wrapper will not be called and instead
    # the original wrapped function will be called directly instead.
    # The 'proxy' argument provides a way of passing a custom version of
    # the FunctionWrapper class used in decorating the function.
