Well, the compiler can't optimize this if you are changing the count inside 
the loop, there's a change of semantics (and behavios) if it does. If the 
method actually returns a cached count, then it's ok to leave it as is. The 
method should be renamed (to GetItemCount or something similar) but maybe 
it's part of the BeAPI and we can't do that. I'd go with a comment above the 
for loop, just so I stop to bug you against these :)
