* parsed.
*
* This parser is most similar to a recursive descent parser. Single
* functions represent discrete grammatical rules for the language, and
* they are able to capture the text that represents those rules.
*
* Consider the function Compiler::keyword(). (All parse functions are
* structured the same.)
*
* The function takes a single reference argument. When calling the
* function it will attempt to match a keyword on the head of the buffer.
* If it is successful, it will place the keyword in the referenced
* argument, advance the position in the buffer, and return true. If it
* fails then it won't advance the buffer and it will return false.
*
* All of these parse functions are powered by Compiler::match(), which behaves
* the same way, but takes a literal regular expression. Sometimes it is
* more convenient to use match instead of creating a new function.
*
* Because of the format of the functions, to parse an entire string of
* grammatical rules, you can chain them together using &&.
*
* But, if some of the rules in the chain succeed before one fails, then
* the buffer position will be left at an invalid state. In order to
* avoid this, Compiler::seek() is used to remember and set buffer positions.
*
* Before parsing a chain, use $s = $this->seek() to remember the current
* position into $s. Then if a chain fails, use $this->seek($s) to
* go back where we started.
