case class Chan(s: String) extends PiObject with Product with Serializable
A pi-calculus channel.
These may be used for communication, they may be communicated themselves, and they are also used as variables.
For instance, channels are used as variables to create patterns of expected inputs and outputs.
For example, a process may expect a pair PiPair(Chan(X),Chan(Y)) as input.
Each of the channels X and Y will (should) eventually be instantiated to a resource.
e.g. receiving input a(X).0 from a matching output 'a<"Hello">.0 creates the instatiation
X --> "Hello".
We apply these instantiations to the pattern PiPair(Chan(X),Chan(Y)) until the
pattern contains no channels/variables. We then know that the input is available and
the process can be executed (pending all other inputs as well).
A process would never receive and/or do anything useful with a pi-calculus channel.
