	// Generator Operators And Vector Operators

	// Generators are operators that have a signature of F(R) => R,
	// taking a given rule and returning another rule, such as 
	// ignore, which parses a given rule and throws away the result.

	// Vector operators are those that have a signature of F(R1,R2,...) => R,
	// take a list of rules and returning a new rule, such as each.

	// Generator operators are converted (via the following _generator
	// function) into functions that can also take a list or array of rules
	// and return an array of new rules as though the function had been
	// called on each rule in turn (which is what actually happens).

	// This allows generators to be used with vector operators more easily.
	// Example:
	// each(ignore(foo, bar)) instead of each(ignore(foo), ignore(bar))

	// This also turns generators into vector operators, which allows
	// constructs like:
	// not(cache(foo, bar))
