Subject: RE: require and case

I've noticed this before, but in a different context:

Consider the following:

# a.rb
class A
	@@createdCount = 0

	def initialize
		@@createdCount += 1
	end

	def A.utilization
		@@createdCount
	end
end

# main.rb
require 'a.rb'

a1 = A.new
p A.utilization	# => 1

# sub.rb
require 'A.rb' # <===== CASE CHANGE

p A.utilization	# => 0 ! OOPS


##############
It appears that because of the case difference, Ruby thinks that this is the
first time loaded and re-evaluates the
class members.

This should definitely be looked at.  I to agree that "require" might want
to be case insensitive.

It took me a while to track this down as the 2 requires were in different
files.

Should require be case insensitive or should it give a warning if the module
it's trying to load has different case to that specified?
