What were you thinking of? I could imagine a predefined class, such as
class copyfuncattrs:
def __init__(self, f):
self.f = f
def __call__(self, func):
res = self.f(func)
res.__name__ = func.__name__
res.__doc__ = func.__doc__
res.__dict__.update(func.__dict__)
return res
This could be used to define a decorator
@copyfuncattrs
def trace(f):
def do_trace(*args):
print "invoking", f.__name__, args
return f(*args)
return do_trace
which in turn could be used to decorate a function
@trace
def hello():
"Print a nice greeting"
print "Hello, world"
which in turn could be called and inspected
hello()
print hello.__doc__
Then, the question is where copyfuncattrs should live, and I would
object that to be yet another builtin.
