Oh really? I thought putting the conditional in the middle was 
ingenious, whoever thought that must have the next Turing award!

I always feel there's something wrong with the (condition ? true : 
false) or (if condition then true else false) expressions found in other 
languages; and just realized it was because of their unnatural ordering. 
I have to admit initially the reversed ordering do confound me, but 
afterward it felt even more natural than the traditional 
"conditional-first" expression.
