StringKeys

A StringKeys object works like a hash, except keys which are not strings are converted to strings.

require 'stringkeys'
sk = StringKeys.new
sk[:name] = 'Fred'
sk.keys[0].class #=> String

The idea is simple. When a key comes in, whether for [] or []=, if it is not a string, then its .to_s method is called and the result is used for the key. So the following lines produce identical results:

sk[MyClass] = 1
sk[:MyClass] = 1
sk['MyClass'] = 1

Installation

gem install stringkeys
