/*
* Solidity Grammar, based on Javascript grammar.
* The following comment is from that grammar:
* ==================
*
* Based on grammar from ECMA-262, 5.1 Edition [1]. Generated parser builds a
* syntax tree compatible with Mozilla SpiderMonkey Parser API [2]. Properties
* and node types reflecting features not present in ECMA-262 are not included.
*
* Limitations:
*
* * Non-BMP characters are completely ignored to avoid surrogate pair
* handling.
*
* * 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. This 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 Annex C are also not applied.
*
* All the limitations could be resolved, but the costs would likely outweigh
* the benefits.
*
* Many thanks to inimino [3] for his grammar [4] 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.
*
* [1] http://www.ecma-international.org/publications/standards/Ecma-262.htm
