I don't like the words neccesary or unneccesary in these discussions,
because they rarely add anything. For instances decorators are
unneccesary in python now, even without multi-line lambdas.
There is nothing you can do with decorators that you can't do
without.

There is no need for special syntax. The decorators are just syntactic
sugar to do something that was already possible before.

Could you give me an example. Suppose I have the following:
def arg_range(inf, sup):
def check(f):
def call(arg):
if inf <= arg <= sup:
return f(arg)
else:
raise ValueError
return call
return check
@arg_range(3, 12)
def func(arg):
return arg
How would this look simpler with multi-line lambda's?
