// 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).
//

// to know when parsing a label, in order to allow or disallow
// continue jumps to that label.

// The following three functions all verify that a node is an lvalue —

//
// - Check that none of the bound/assigned-to identifiers are reserved words.
// - 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
// additionally a checkClashes object may be specified to allow checking for
// duplicate argument names. checkClashes is ignored if the provided construct
// is an assignment (i.e., bindingType is BIND_NONE).
