BEFORE YOU START ===

Read the Ruby Hacking Guide chapter 11, available in English at whitequark.org/blog/2013/04/01/ruby-hacking-guide-ch-11-finite-state-lexer/

Remember two things about Ragel scanners:

1) Longest match wins.

2) If two matches have the same length, the first
   in source code wins.

General rules of making Ragel and Bison happy:

* `p` (position) and `@te` contain the index of the character
  they're pointing to ("current"), plus one. `@ts` contains the index
  of the corresponding character. The code for extracting matched token is:

     @source_buffer.slice(@ts...@te)

* If your input is `foooooooobar` and the rule is:

     'f' 'o'+

  the result will be:

     foooooooobar
     ^ ts=0   ^ p=te=9

* A Ragel lexer action should not emit more than one token, unless
  you know what you are doing.

* All Ragel commands (fnext, fgoto, ...) end with a semicolon.

* If an action emits the token and transitions to another state, use
  these Ragel commands:

     emit($whatever)
     fnext $next_state; fbreak;

  If you perform `fgoto` in an action which does not emit a token nor
  rewinds the stream pointer, the parser's side-effectful,
  context-sensitive lookahead actions will break in a hard to detect
  and debug way.

* If an action does not emit a token:

     fgoto $next_state;

* If an action features lookbehind, i.e. matches characters with the
  intent of passing them to another action:

     p = @ts - 1
     fgoto $next_state;

  or, if the lookbehind consists of a single character:

     fhold; fgoto $next_state;

* Ragel merges actions. So, if you have `e_lparen = '(' %act` and
  `c_lparen = '('` and a lexer action `e_lparen | c_lparen`, the result
  _will_ invoke the action `act`.

  e_something stands for "something with **e**mbedded action".

* EOF is explicit and is matched by `c_eof`. If you want to introspect
  the state of the lexer, add this rule to the state:

     c_eof => do_eof;

* If you proceed past EOF, the lexer will complain:

     NoMethodError: undefined method `ord' for nil:NilClass
