This is probably a bad idea since isset() needs to return true or false
for each argument it receives. (Any other mode of operation is too
complicated).
This means that you need to return the values for each variable as an
array and that each value from the array needs to be tested. This results
in more typing than you would previously have been doing and is more
computationally intensive.
I suggest just stick with the current implementation.
