We seem to be in basic agreement. Depending on what the user's goal is, he
may not care much about how the code looks like as long as it does what the
user wants. I was assuming a user who wants to understand how it works, i.e.
the bpl idioms themselves (in this particular case).

Suggesting to use a tool to generate code in language X by using language
Y makes indeed a lot of sense if Y reflects the vocabulary of the user
(i.e. the 'problem domain') better than X.
