#includes ##before: enum.each do |e|   if e == "1"     #bla~     #bla~   end end

##after: enum.includes("1"). do   #bla~   #bla~ end

#anies ##before: enum.each do |e|   if e.id == "1"     #bla~     #bla~   end end

##after: enum.anies(id == "1"). do   #bla~   #bla~ end

#includes ##before: enum.each do |e| if e == "1" #bla~ #bla~ end end

##after: enum.includes("1"). do #bla~ #bla~ end

You can also do this with:

enum.select { |e| e == "1" }.each do ...

so your 'includes' function could be written as:

class Enumerable   def includes(o, &block)     select { |e| e == o }.each(&block)   end end

#anies ##before: enum.each do |e| if e.id == "1" #bla~ #bla~ end end

##after: enum.anies(id == "1"). do #bla~ #bla~ end

I don't think this will even parse - passing bare code fragments like that doesn't work in Ruby.
