Additional notes (May, 2023)

During additional discussion on the EWG reflector, Alisdair Meredith expressed that he intends to propose that some alternative tokens be treated as full keywords in phase 7, to prevent and from being used as an rvalue reference and compl from being used for naming destructors. That would reverse the above direction.

Furthermore, an idea was floated to treat all alternative tokens as full keywords in phase 7 and as identifiers in phase 4, amending the grammar productions for expressions as necessary. This removes the special treatment of alternative tokens entirely, however the treatment of examples such as #define and blah would change from ill-formed to well-formed. Some opposition was voiced against changing the phase 4 treatment of alternative tokens.
