Flay is Coming

Imagine having a tool that points out these two methods as potential duplicates and therefore candidates for refactoring:

def save(path)
  File.open path, 'wb' do |f|
    f.write to_blob
  end
end

versus:

def write(file); File.open(file, 'wb') { |f| f.write to_s }; end

Are they different? Sure! One calls #to_s and the other calls #to_blob. Is that enough difference to not consider them for refactoring? No, not in the slightest...

Flay... it is coming...
