If you're comparing a key to a list ( function above ) why should it 'fail'? It's either T or nil and can accept multiple datatypes to test. Perhaps happiness is not in the cards for you. Have a nice weekend.
How should I know why it `has to fail'?! I asked several different times/ways.
I agree (and the "Key comparison method" is one of the most efficient methods for this task) but I was told otherwise when I raised that very point.
You ask; I don't have the reputation points to get a reply.
Wait a minute. If happiness isn't in the cards for me do you really think my weekend will be nice?
