Attempt at a zippier HashWithIndifferentAccess for Ruby MRI (c) 2009 Lourens Naudé (methodmissing), James Tucker (raggi) http://github.com/methodmissing/hwia This library works with Ruby MRI > 1.8.6 && 1.9.2 and is a more efficient implementation of ActiveSupport::HashWithIndifferentAccess, which allows interchangeable use of string and symbol hash keys.

'require "hwia_rails"' from within an initializer There's no step three, however, if the gem hasn't built due to github queue delays today (22/08/2009), clone, 'rake gem' and install. It's unlikely you'd see these improvements for most apps as at the framework level, especially for Rails 3.0, this mostly negates query params access overheads.Any pointers and refactoring suggestions much appreciated. Have fun, happy hacking!
