function simulateRevoke(required any currentPerms, required any toRemove) {
var trial = currentPerms.clone();
setRemoveAll(trial, toRemove);
return trial;
}
current = setNew();
current.add("READ");
current.add("WRITE");
current.add("ADMIN");
remove = setNew();
remove.add("ADMIN");
trial = simulateRevoke(current, remove);
writeOutput(current.has("ADMIN")); // true — unchanged
writeOutput(trial.has("ADMIN")); // false
</cfscript>
