/// @assertion Assignable expressions are expressions that can appear on the

///   super unconditionalAssignableSelector |
///   identifier
/// ;
/// unconditionalAssignableSelector:
///   '[' expression ']' |
///   '.' identifier
/// ;
/// assignableSelector:
///   unconditionalAssignableSelector |
///   '?.' identifier

/// An assignable expression is either:
/// • An identifier.
/// • An invocation (possibly conditional) of a getter or list access operator
///   on an expression e.
/// • An invocation of a getter or list access operator on super.
/// @description Checks that super without unconditionalAssignableSelector can't
