A ruby method can accept two blocks as arguments, if we convert them to procs or lambdas

	#!/bin/ruby

	# Inspired by http://innig.net/software/ruby/closures-in-ruby

	# Can this take 2 blocks?
	# def apply_two_things(&block1, arg_after_block)
	# end
	# syntax error, unexpected ',', expecting ')'

	# What about 2 procs?

Notes on findutils

	# This is not the official way to prune directories, but I found it easier.
	# It prints the contents of all the files in the tree - excluding .git and CachedPixmaps,
	# but there is a potential bug in the second globbed file name
	#
	# Works with GNU findutils. Might not work with BSD find, such as Mac OS X.
