However if you try something like

[mark@laptop ruth-0.10]$ ruby tests/parse_ruby_file.rb 'def m(a); x=1; end'
Def
  :m
  [:a, :x]
  LocalAssign
    :x
    IntegerLiteral
      1

So it seems that the array [:a, :x] is a list of all local variables used in 
the function.

Is there any way to find out what parameters the function takes?
