// When an assignment expression position starts with an left parenthesis, the determination of the type
// of the syntax is to be deferred arbitrarily long until the end of the parentheses pair (plus a lookahead)
// or the first comma. This situation also defers the determination of all the expressions nested in the pair.
//
// There are three productions that can be parsed in a parentheses pair that needs to be determined
// after the outermost pair is closed. They are:
//
// 1. AssignmentExpression
// 2. BindingElements
// 3. AssignmentTargets
//
// In order to avoid exponential backtracking, we use two flags to denote if the production can be
// binding element or assignment target.
//
// The three productions have the relationship:
//
// 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
// pattern. The CoverInitializedName check is deferred.
