// 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))
