closures without a return throws confusing error message

perhaps a new function for casting the closure result to a Boolean which checks null and doesn’t cast it to a string, instead throwing a Closure didn’t return a Boolean value?

I've checked this ticket with lucee latest version 5.3.8.117-SNAPSHOT also. Yes, the error message "Can't cast String [] to a boolean" is confusing when using structSome closure without a return. And same error throws for structEvery,arrayEvery,arraySome also.
