Subject: Adding sugar to Ruby

Hi, I've collected some nice little additions to Ruby and put them in a
gem called zucker.

Some of the features:

* control structure like iteration:

iterate [1,2], [3,4,5] do |e,f|
  puts "#{e},#{f}"
end
# outputs
#  1,3
#  2,4
#  ,5

* Regexp.union shortcut

/Ruby\d/ | /test/i | "cheat"
# creates a Regexp similar to:
#  /(Ruby\d|[tT][eE][sS][tT]|cheat)/

* Blocks, where nil can be egocentric

egonil do
  nil.some_methods.that[:do].not.exist
end # => nil

* Array#to_proc

[1,2,3].map &[:*, 5]  # => [5, 10, 15]

* More at http://rubyzucker.info / http://github.com/janlelis/zucker

What's your opinion about these methods?
