This is something that will exist in ruby 1.9. I was using it to create the
data folder. Slight rewrite from one of your samples:
def data_path
> @data_path||=lambda do
> RUBY_PLATFORM =~ /win32/ ? File.expand_path(Dir.getwd) :
> File.expand_path(File.join("~", ".rudolph"))
> end.call.tap{|udd| Dir.mkdir(udd) unless File.exist?(udd)}
> end

This should work. I just defined tap in the source. Anyway it doesn't
The reason it is important for this to work is to make the code work better.
This way we just do all those calculations if data_path is not present. And
mkdir something like a sideeffect so it makes sense to be in a tee (tap,
whatever) clause.
Object.respond_to?(:tap).to_s

Any ideas? I'm still a newbie on shoes :\
