* An IndexedSourceMapConsumer instance represents a parsed source map which

* that it takes "indexed" source maps (i.e. ones with a "sections" field) as
* input.
*
* The first parameter is a raw source map (either as a JSON string, or already
* parsed to an object). According to the spec for indexed source maps, they
* have the following attributes:
*
* - version: Which version of the source map spec this map is following.
* - file: Optional. The generated file this source map is associated with.
* - sections: A list of section definitions.
*
* Each value under the "sections" field has two fields:
* - offset: The offset into the original specified at which this section
* begins to apply, defined as an object with a "line" and "column"
* field.
* - map: A source map definition. This source map could also be indexed,
* but doesn't have to be.
*
* Instead of the "map" field, it's also possible to have a "url" field
* specifying a URL to retrieve a source map from, but that's currently
* unsupported.
*
* Here's an example source map, taken from the source map spec[0], but
* modified to omit a section which uses the "url" field.
*
* {
* version : 3,
* file: "app.js",
* sections: [{
* offset: {line:100, column:10},
* map: {
* version : 3,
* file: "section.js",
* sources: ["foo.js", "bar.js"],
* names: ["src", "maps", "are", "fun"],
* mappings: "AAAA,E;;ABCDE;"
* }
* }],
* }
*
* The second parameter, if given, is a string whose value is the URL
* at which the source map was found. This URL is used to compute the
* sources array.

// 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.

// 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.
