wadus :wadus => "wadus"
# wadus = {:wadus=>"wadus"}

# Instead of what I wanted which is:
# wadus = nil
# options = {:wadus=>"wadus"}

# In Rails I've seen things like:

def jander(wadus = nil, options = {})
  if wadus.is_a?(Hash)
    options = wadus
    wadus = nil
  end
  puts "wadus = #{wadus.inspect}"
  puts "options = #{options.inspect}"
end

jander
# wadus = nil
# options = {}
# OK

jander "wadus"
# wadus = "wadus"
# options = {}
# OK

jander "wadus", :wadus => "wadus"
# wadus = "wadus"
# options = {:wadus=>"wadus"}
# OK

jander :wadus => "wadus"
# wadus = nil
# options = {:wadus=>"wadus"}
# OK
# But that's ugly man!!
