Ruby 1.8 "supports" this coding style however using hashes, for example:

def fun(params)
  return "#{params[:a]} #params[:b]"
end

Print fun(:a => 1, :b => 2)

No. Keyword arguments like 

   fun(b:20, a:10)

is planned, but named keyword arguments will be separated from
positional arguments still.
