Sean James, yes of course there are times that it is _needed_. Agreed. I just would never opt for using tools like declare and letfn as the _go to tool_. I think of cyclic dependencies as less simple, harder to grok etc. When you need it, by all means have the power to do so, but when you don't need it, then no need for adding extra mental weight for code-readers to have to go through to understand your code.
