// easy to recognize.

// expressions and divisions. It is set on all token types that can
// be followed by an expression (thus, a slash after them would be a
// regular expression).

// The `startsExpr` property is used to check if the token ends a
// `yield` expression. It is set on all token types that either can
// directly start an expression (like a quotation mark) or can
// continue an expression (like the body of a string).

// - Record name declarations for bindings in the appropriate scope.
// - Check duplicate argument names, if checkClashes is set.
//
// If a complex binding pattern is encountered (e.g., object and array
// destructuring), the entire pattern is recursively checked.
//
// There are three versions of checkLVal*() appropriate for different
// circumstances:
//
// - checkLValSimple() shall be used if the syntactic construct supports
// nothing other than identifiers and member expressions. Parenthesized
// expressions are also correctly handled. This is generally appropriate for
// constructs for which the spec says
//
// > It is a Syntax Error if AssignmentTargetType of [the production] is not
// > simple.
//
// It is also appropriate for checking if an identifier is valid and not
// defined elsewhere, like import declarations or function/class identifiers.
//
// Examples where this is used include:
// a += …;
// import a from '…';
// where a is the node to be checked.
//
// - checkLValPattern() shall be used if the syntactic construct supports
// anything checkLValSimple() supports, as well as object and array
// destructuring patterns. This is generally appropriate for constructs for
// which the spec says
//
// > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
// > an ArrayLiteral and AssignmentTargetType of [the production] is not
// > simple.
//
// Examples where this is used include:
// (a = …);
// const a = …;
// try { … } catch (a) { … }
// where a is the node to be checked.
//
// - checkLValInnerPattern() shall be used if the syntactic construct supports
// anything checkLValPattern() supports, as well as default assignment
// patterns, rest elements, and other constructs that may appear within an
// object or array destructuring pattern.
//
// As a special case, function parameters also use checkLValInnerPattern(),
// as they also support defaults and rest constructs.
//
// These functions deliberately support both assignment and binding constructs,
// as the logic for both is exceedingly similar. If the node is the target of
// an assignment, then bindingType should be set to BIND_NONE. Otherwise, it
// should be set to the appropriate BIND_* constant, like BIND_VAR or
// BIND_LEXICAL.
//
// If the function is called with a non-BIND_NONE bindingType, then

// duplicate argument names. checkClashes is ignored if the provided construct
