Back to that old Whitesmith's compiler.  It's certainly very interesting 
to see what the assembler looks like when you forget the ampersand, the 
compiler doesn't throw an error, and so the entire structure instead of 
a single pointer gets passed into your function.  Not so much passed by 
value, or reference, or object, but complete foul up :)
