This script builds a set of unique values from the argument list and prints its contents.
# import what we need from the appropriate modules
import crack.cont.hashmap HashMap;
import crack.io cout;
import crack.strutil StringArray;
import crack.sys argv;
## Cheesey set implementation.
class ArgSet : HashMap[String, bool] {
oper init(StringArray args) {
for (arg :in args)
this[arg] = true;
}
void dump() {
for (item :in this)
cout `got $(item.key)\n`;
}
}
# initialize the arg set from the actual args
ArgSet a = {argv};
# write the set
a.dump();
