define pronouns

For pronouns beyond the standard four sets, you declare a named set. Each set has exactly five rows (subject, object, possessive, possessive-pronoun, reflexive), which you may list in any order, and you refer to the set by name from a person's pronouns line. Missing or duplicate rows, shadowing a standard set, and redefinition are all compile errors.
