I've long felt that types define how actual values are represented and
operators/actors define the computation between ideal values.
I therefore feel that when I define a 'modulo 2-pi' data type
that all arithmetic should respect this type specification. I
do not want to create a new set of actors for what is fully defined
by the type mapping from results computed in the unconstrained number
space/line without regard to the output type, and the constrained number
space/line enforced by the 'modulo 2-pi' output type.
Similarly I do not want to have to replicate actors just to change
rounding mode.
The extreme polymorphism of its actors is one of Ptolemy II's major
benefits (and problems), it seems a shame not to preserve and exploit
the design space positioning.
