I don't have issues with `for/and`; moreover, I do not wish for Racket to be
lazy by default, or uber-functional, or dependently typed, or anything else
which Haskell or another language is. I understand the tradeoffs. What I
don't understand is why I seem to be expected to start a discussion about
those tradeoffs when I simply want to say “here's when lack of laziness
bites”. I don't intend to make any judgements, and it's a pity that people
still see them whenever I say anything more emotional than “it is how it
is”.

I'll include this whole paragraph verbatim as a disclaimer for the whole
series, if you don't mind (even tho it's a bit upsetting to see you telling
me all these obvious things as if there was a chance that I think
documentation writers are at fault for my misunderstandings and mistakes, or
that I think some of the perceived issues I have with Racket are due to it
being stupid, or that I want it to be a Haskell clone, or that I'm trying to
learn it a why-isn't-it-Haskell-Racket).

As per customs and traditions of Internet White Knights, I feel obliged to
reply that there's Debug.Trace module which makes it a considerably easier
task (and it's the second result when googling “haskell debug”, too).

Thanks, noted. (I updated the post.)
