Useful for cascaded optionality, e.g.: static S printableUserName() { // Custom or Slack name, depending on what's available ret or((S) callOpt(getBot("#1002355"), "getUserName"), getUserName()); }	2016-01-27 01:28:45

getOpt can be passed a null 1st argument - then it just returns null. Useful for cascaded optionality, e.g.:

static S printableUserName() {
// Custom or Slack name, depending on what's available
ret or((S) callOpt(getBot("#1002355"), "getUserName"), getUserName());
}
