I idea is good but may I suggest it be a little less "cryptic"?
Something more like:

  def meth *parm
     parm = Parameters.new(parm) do
       args :foo, :bar, :request => 'useless'
       keys :side => nil, :meat => 'fish'
     end
     parm.foo
     ...

You could also to set parm automatically, and of course a #parameters
constructor method is fine if you prefer, producing:

  def meth *parm
     parameters(parm) do
       args :foo, :bar, :request => 'useless'
       keys :side => nil, :meat => 'fish'
     end 
     parm.foo
     ...
