I can imagine an implementation that doesn't bind <record name> at all, but rather extends the type-descriptor syntax to match a literal <record name>, ie, (define-syntax type-descriptor (syntax-rules (<record-name>) ((type-descriptor <record-name>) ,,,))) But, I think that just brings us back to Andre's original question about exporting the names of literals.
