Can I undecorate a function?

[Matthew Wilson]

The decorator as_string returns the decorated function's value as
string. In some instances I want to access just the function f,
though, and catch the values before they've been decorated.

Is this possible?

def as_string(f):
def anon(*args, **kwargs):
y = f(*args, **kwargs)
return str(y)
return anon

@as_string
def f(x):
return x * x

Untested:
def as_string(f):
def anon(*args, **kwargs):
y = f(*args, **kwargs)
return str(y)
andon.the_function = f
return anon
@as_string
def f(x):
return x * x

print f.the_function(10)

Call the one you want.

or just
fs = as_string(f)

It's much simpler not to use the decorator syntax if you also want
access to the original function.

Simply declare f as a function, then assign decorator(f) to some other name.
