// The assignment of fine-grained, information-carrying type objects

// token in a way that is very cheap for the parser to look up.

// All token type variables start with an underscore, to make them
// easy to recognize.

// The `beforeExpr` property is used to disambiguate between regular
// 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).
//
// `isLoop` marks a keyword as starting a loop, which is important
// to know when parsing a label, in order to allow or disallow
// continue jumps to that label.

// - 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 = …);
