As my knowledge of Object#send stands now: it can't recreate the full
breadth of method invocations in ruby. Object#send should accept an
optional parameter:
[1,2,3].send(:collect, :block => lambda{|x| x.to_s+"!"})
That obviously wouldn't work because it's still ambiguous. Oh well.
I'll just extend the nokogiri class! Thanks for playing everyone!
