 Rules need to be separated only by whitespace (their beginning is easily
 recognizable), but a semicolon (“;”) after the parsing expression is allowed.
 
-Rules can be preceded by an *initializer* — a piece of JavaScript code in curly
-braces (“{” and “}”). This code is executed before the generated parser starts
-parsing. All variables and functions defined in the initializer are accessible
-in rule actions and semantic predicates. The code inside the initializer can
-access the parser object using the `parser` variable and options passed to the
-parser using the `options` variable. Curly braces in the initializer code must
-be balanced. Let's look at the example grammar from above using a simple
