Re:  Looking for a concise way of specifying an  condit
Thank you Andrew, Michael and Ken!

I use value-of so much I forgot about it's impact on "non-strings".
This information also helped me with a very similar issue I just ran
into today where I was writing a function that was returning a boolean
true or false, but it was always true... because value-of was turning
it into a string.
