Wrong way to deal with the 1.9.2 removal of . from the loadpath:

1. require "./foo/bar" forces you to run code from your project root
2. $LOAD_PATH.unshift(".") recreates security issue, and pollutes

Right way to deal with the 1.9.2 removal of . from the loadpath:

1. require_relative "foo/bar" if you don't need Ruby 1.8 compatibility

You should never do this in a source file included with your library,
app, or tests:

    require 'rubygems'

The system I use to manage my $LOAD_PATH is not your library/app/tests
