(Otherwise, seeing > "*" followed by "|" is ambiguous until you look at the *next* token.) Hi, I’m not objecting, but shouldn’t LL(1) be only an implementation concern? AFAICT, it is not detectable whether an implementation parses "||" as a single token, or looks ahead for two delim tokens. Can something undetectable make an implementation non-conforming? -- Simon Sapin
