// 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.

|
// 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))
