* "undefined" rather than have the bug in the error path crash the
* program (making the first bug harder to identify). For that reason,

// after the outermost pair is closed. They are:
//
// 1. AssignmentExpression
// 2. BindingElements

// binding element or assignment target.

//
// BindingElements AssignmentTargets AssignmentExpression
//
// with a single exception that CoverInitializedName when used directly in an Expression, generates
// an early error. Therefore, we need the third state, firstCoverInitializedNameError, to track the
// first usage of CoverInitializedName and report it when we reached the end of the parentheses pair.
//
// isolateCoverGrammar function runs the given parser function with a new cover grammar context, and it does not
// effect the current flags. This means the production the parser parses is only used as an expression. Therefore
// the CoverInitializedName check is conducted.
//
// inheritCoverGrammar function runs the given parse function with a new cover grammar context, and it propagates
// the flags outside of the parser. This means the production the parser parses is used as a part of a potential
