*
* At several stages in the code generation a node of type
* "be_operation" is visited, and the code for its arguments must
* be generated.
* Sometimes the argument declarations must be generated (such as
* in the class declaration), other the arguments names (such as
* in method invocations).
* This class implements some common functionality required across all
* argument visitors
