Determine the set of arguments, for an operator, that are variables.

playis the player for this operation sequence.
i_opis the operator index. If this operator is part of a user function call, it must be the first UserOp in the call. (There is a UserOp at the beginning and end of each call.)
variableis the set of argument variables corresponding to this operator. If the operator is a UserOp, the arguments are the variables that are passed into the function call.
workthis is work space used by arg_variable to make subsequent calls faster. It should not be used by the calling routine. In addition, it is better if work does not drop out of scope between calls.
