This plugin provides a text-object 'a' (argument). You can
d(elete), c(hange), v(select)... an argument or inner argument in familiar ways.
That is, such as 'daa'(delete-an-argument) 'cia'(change-inner-argument) 'via'(select-inner-argument).
What this script does is more than just typing
  F,dt,
because it recognizes inclusion relationship of parentheses.

There is an option to descide whether the motion should go out to toplevel function or not in nested function application.

Examples:
  case1) delete An argument
      function(int arg1,    ch<press 'daa' here>ar* arg2="a,b,c(d,e)")
      function(int arg1<cursor here; and if you press 'daa' again..>)
      function(<cursor>)

  case2) change Inner argument
      function(int arg1,    ch<press 'cia' here>ar* arg2="a,b,c(d,e)")
      function(int arg1,    <cursor here>)
      
  case 3) smart argument recognition (g:argumentobject_force_toplevel = 0)
       function(1, (20<press 'cia' here>*30)+40, somefunc2(3, 4))
       function(1, <cursor here>, somefunc2(3, 4))
       
       function(1, (20*30)+40, somefunc2(<press 'cia' here>3, 4))
       function(1, (20*30)+40, somefunc2(<cursor here>4))

  case 4) smart argument recognition (g:argumentobject_force_toplevel = 1)
       function(1, (20<press 'cia' here>*30)+40, somefunc2(3, 4))
       function(1, <cursor here>, somefunc2(3, 4)) " note that this result is the same of above.
       
       function(1, (20*30)+40, somefunc2(<press 'cia' here>3, 4))
       function(1, (20*30)+40, <cursor here>) " sub-level function is deleted because it is a argument in terms of the outer function.
