The point is that at the moment to set this sort of api up requires a lot of
work, defeating 50% of the value i.e. to define a new function with the
attribute access behaviour requires defining each individual function to return
a middle step object that has the attribute of the next function, so you can't
define a function in plain english.
e.g.
def insert_into(x, y):
...
def insert(x):
class Return:
def into(self, y):
return insert_into(x, y)
return Return()
insert.into = insert_into
is a very long way to say:
def insert(x)._into(y):
...
and that is without the actual logic and for only 2 positional args.

The point is so that in code that expects dynamically called functions or to be
able to reference the function by name it needs to have a single name that
follows backward compatible naming conventions. I would be happy with it being
on the onus of the developer in question to add a wrapping function, less happy
than if it was added by default but it would still be a saving (and could maybe
be in a decorator or something).

I know lots of people that have had this reaction but just shrugged it off as
"the way things are", which would seem like a good way to stagnate a language,
so I thought I would ask.
