With one colleague I discovered that the decorator code is always
executed, every time I call
a nested function:
def dec(fn):
print("In decorator")
def _dec():
fn()
return _dec
def nested():
@dec
def fun():
print("here")
nested()
nested()
Will give:
In decorator
In decorator
So we were wondering, would the interpreter be able to optimize this
somehow?
I was betting it's not possible, but I'm I would like to be wrong :)
