[issue36953] Remove collections ABCs?

[Matthias Bussonnier]

Matthias Bussonnier <bussonniermatthias at gmail.com> added the comment:

Should it still raise an informative error message with ImportError:

> ImportError: cannot import name 'XXX' from 'collections', please import it from 'collections.abc'.

or just the "cannot import name 'XXXX'" without the  "please import it from 'collections.abc'." ?
