Nice way to add reloading support to a ruby gem's top-level module

gistfile1.rb

module Foo

	def self.files
		f = []
		f << 'foo/a'
		f << 'foo/b'
		f
	end

	def self.load_relative(f)
		path = "#{File.join(File.dirname(caller[0]), f)}.rb"
 	  load path 
	end

	def self.reload!
		files.each { |f| load_relative f }
	end

end

# normal loading during require
Foo.files.each { |f| require_relative f }

# reloading in irb
Foo.reload!
