... It needs to add 'None' as an alternative to all other places where currently NAME occurs.

Fudge. None makes no sense anywhere in, e.g.,

dotted_name: NAME ('.' NAME)*

or

global_stmt: 'global' NAME (',' NAME)*

but I suppose it has to be allowed for in 2.3 anyway else an existing

import None.None.None as None

would yield a SyntaxError instead of a warning.

Note too that we can't change the generated code at all for 2.3 unless under the control of a new future statement, else existing None-abusing code could break.
