Well, pascal is a typed language, so while I do realize that the 
information is stored as false=0 and true=1, and that's how the array 
is indexed internally when I make such a declaration, I expect a pascal 
compiler to treat the boolean type intelligently. (It usually does :)

I did cast it to boolean! That's why it smells like a bug.
