And finally a new version of if-first-iteration:

That's more or less that, minor a few points (a documentation string, bind step-body after first-usage to avoid setf, usage of make-accum-var-binding, and probably eliminate the no-else code generation test (let the compiler do that)).

I'll add it to the next version (not immediately, I'm too busy right now). I hope this is ok. BTW, what's the iteration pattern that lead you to define this and not use IF-FIRST-TIME? Could you show some sample/imaginary code?

Thanks for your contribution.
