[issue21642] "_ if 1else _" does not compile

[Martin v. Löwis]

Martin v. Löwis added the comment:

For those who want to skip reading the entire SO question: "1else" tokenizes as "1e" "lse", i.e. 1e is considered the beginning of floating point literal. By the description in the docs, that should not happen, since it is not a valid literal on its own, so no space should be needed after the 1 to tokenize it as an integer literal.
