Ahhhh. I now perceive the Ruby Way.

So I should not have been finding the type at all, 
but letting the language do the work for me.

Still, it bothers me a little that x==y does not always
imply x===y. But I will just have to get used to that...

Actually I have trouble remembering what === means --
whether to say x === y or y === x, which are of course
not the same.

Thanks much,
Hal
