My language does that. I'd be very surprised if it was the only one in
existence that does so.
I would be. That means that
func(x)
and
tmp = x
func(tmp)
behave differently,
Not as far as func() is concerned. But overall there is a difference
because now tmp contains a copy of x. (Also, if x contains a list for
example, func() can modify the copy in tmp, not in x. But this shouldn't
be surprised because the code is different!)
Really?
>>> x=[1,2,3]
>>> tmp=x
>>> def func(thing):
... thing.clear()
...
>>> func(tmp)
>>> tmp
[]
>>> x
[]

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.
