This behaviour isn't possible but you can simulate it. Use a private
array variable in your method. If you want to create an new "variable"
then add an element to that array. Second, define your own configure
method.

ex:

class A {
  private variable _myvars
  method myconfigure {varname {value {}}} {
    if {[string equal {} $value]} then {
      return $_myvars($varname)
    } else {
      set _myvars($varname) $value
    }
  }
}
