Function remove_meaning_global 

Source
pub fn remove_meaning_global(token: &Token)
Expand description

Remove a token’s meaning entirely — the token becomes undefined, as if it had never been defined, so a later use takes the normal undefined-CS error path naming the token itself. Bypasses the group-undo journal: intended ONLY for format-bootstrap time (no user groups open), where a format layer retracts a definition inherited from a lower layer that the emulated format must not expose (e.g. plain.tex’s \+ in a LaTeX session — real LaTeX is INITEX-based and never defines it).
