Please don't reopen an issue if it was closed by a core developer.
It's not clear to me what exactly do you want to change in the implementation
or documentation.
A sequence of three periods has a special meaning as an ellipsis literal.
is literally describes how the ELLIPSIS token is identified in
Parser/tokenizer.c (see PyToken_ThreeChars in that file) So a sequence of three
periods is identified as an ellipsis literal which is an expression in Python.
Do you want to change tokenize.tokenize() (it's in Lib/tokenize.py) so it will
return
TokenInfo(type=52 (ELLIPSIS), ...)
instead of
TokenInfo(type=53 (OP), ...)
? Note that ELLIPSIS has been added to tokenize.EXACT_TOKEN_TYPES in issue
24622. To me, since it has been added to tokenize.EXACT_TOKEN_TYPES there is no
need to special case ELLIPSIS in Lib/tokenize.py.
Or do you want to clarify
To simplify token stream handling, all Operators and Delimiters tokens are
returned using the generic token.OP token type.
