Yes, and it would not solve anything. :-|   (the contents are not the 
problem)

I'm not at all sure about the first, as the "next" pointer (for the 
iteration) doesn't need to be replaced (assuming that its retrieved and 
stored somewhere as part of advancing to the current item).

The problem with a "for i=0 to dict.count-1" loop is that it both will skip 
the item after the one thats being removed, and it will not adjust the "upto 
here" part of the for loop to the new size of the array.

Looping backwards makes both of those problems disappear.

... and thats what my head was - unneeded - stuck on. :-\
