Overview

Create me with a String, and I wrap the string, forwarding method invocations to it. Call “permute” and I’ll run through my Modifier chain to derive a new value (for instance, tripling the number of characters).

Constructor Details

#initialize(base = nil, stack = []) ⇒ Mutator

base is usually a String (like “helu”) or Fixnum. Stack is a set of modifier objects (or class names, if you just want to use the defaults). A Mutator with an empty Modifier stack doesn’t do anything and behaves just like an ordinary String or Fixnum.

def initialize(base=nil, stack=[])
    @base = base

Dynamic Method Handling
