Class CommClause
A comm clause, that is, a case
or default
clause in a select
statement.
Examples:
case i1 = <-c1:
print("received ", i1, " from c1\n")
case c2 <- i2:
print("sent ", i2, " to c2\n")
case i3, ok := (<-c3): // same as: i3, ok := <-c3
if ok {
print("received ", i3, " from c3\n")
} else {
print("c3 is closed\n")
}
default:
print("no communication\n")
