Yes, very good hint.
Apart for implementing higher level message, there is mostly one reason 
to use to:do: and it is often a bad one (I abused of, myself):
It is used to optimize code with some sort of inlining that can 
eliminate creation of blocks and squeeze the cost of a few message sends...
The danger is to make code inexpressive, longer than necessary, and not 
extensible to some other collection class.
Let us not optimize code prematurely!
