jamiew / lazily calculated mixin.rb

Created August 22, 2008 23:57

Allows attributes to be declared as lazy, meaning that they won't be # computed until they are asked for

	# pseudoforked from mojombo: http://rubyisawesome.com/2007/10/13/lazy-mixin

	# Before you ask--yes, this has a very specific use case and is not
	# generally applicable to the problem of fine-grained lazy evaluation.
	# But it does exactly what I need it to do. =)

	# Allows attributes to be declared as lazy, meaning that they won't be
	# computed until they are asked for. Just mix this module in:
	#
	# class Foo
