Unlikely. As I recall Python deliberately uses only a
lookahead-1 to resolve ambiguities.
Or see PEP 202
] BDFL Pronouncements

It could be made an arbitrary lookahead in theory, but
as I recall Guido has also said doesn't want that because
it makes human parsing more complex as well.
Can't find a ready citation for that though.
