          | *T.G                   Recursion with label T, body G

          | T                      Type variable

          | end                    End type

### Local Types

    L   ::= Q &{ ?l(U).L, ... }    Branching, receive l(U) from role Q

          | P +{ !l(U).L, ... }    Selection, send l(U) to role P

          | *T.L                   Recursion with label T, body L

          | T                      Type variable
