/*
* JavaScript parser based on the grammar described in ECMA-262, 5th ed.
* (http://www.ecma-international.org/publications/standards/Ecma-262.htm)
*
* The parser builds a tree representing the parsed JavaScript, composed of
* basic JavaScript values, arrays and objects (basically JSON). It can be
* easily used by various JavaScript processors, transformers, etc.
*
* Intentional deviations from ECMA-262, 5th ed.:
*
* * The specification does not consider |FunctionDeclaration| and
* |FunctionExpression| as statements, but JavaScript implementations do and
* so are we. This syntax is actually used in the wild (e.g. by jQuery).
*
* Limitations:
*
* * Non-BMP characters are completely ignored to avoid surrogate
* pair handling (JavaScript strings in most implementations are AFAIK
* encoded in UTF-16, though this is not required by the specification --
* see ECMA-262, 5th ed., 4.3.16).
*
* * One can create identifiers containing illegal characters using Unicode
* escape sequences. For example, "abcd\u0020efgh" is not a valid
* identifier, but it is accepted by the parser.
*
* * Strict mode is not recognized. That means that within strict mode code,
* "implements", "interface", "let", "package", "private", "protected",
* "public", "static" and "yield" can be used as names. Many other
* restrictions and exceptions from ECMA-262, 5th ed., Annex C are also not
* applied.
*
* * The parser does not handle regular expression literal syntax (basically,
* it treats anything between "/"'s as an opaque character sequence and also
* does not recognize invalid flags properly).
*
* * The parser doesn't report any early errors except syntax errors (see
* ECMA-262, 5th ed., 16).
*
* At least some of these limitations should be fixed sometimes.
*
* Many thanks to inimino (http://inimino.org/~inimino/blog/) for his ES5 PEG
* (http://boshi.inimino.org/3box/asof/1270029991384/PEG/ECMAScript_unified.peg),
* which helped me to solve some problems (such as automatic semicolon
* insertion) and also served to double check that I converted the original
* grammar correctly.
