If you're going to have holes, you might consider a struct that just happens
to have numeric keys. Then you can use structKeyExists.
Short of that, I think you'd probably have to dereference the array index in
a CFTRY..CFCATCH block, catch the error, and react to that. Wrap it in a
function named 'isArrayElementDefined' or something, and you should be set.
