I can't speak for Germany, nor even for modern UK practice,
but personally I didn't meet set definition syntax until the
end of second year high school (about 14) and had the
opportunity to drop math (and major on say sciences/engineering
instead) very soon after. Thus it is entirely possible that
I could have gone thru' school with only a brief exposure to
set building notation. (We had of course covered set theory
with Venn diagrams, Union symbols etc but not the set
definition syntax resembling comprehensions...) In fact I
personally kept up math and thus had exposure through the next
3 years until I went off to earn a living!
Then, 9 years after leaving school I went back to University
and studied Electrical Engineering with compulsory math each
year for 4 years. I think I only saw set notation being used
a handful of times and it certainly wasn't needed to pass
the exams. My point being that in my own experience it is
very easy to become a professional engineer/programmer
without much exposure to set builder notation and in
that case list comprehensions are far from being
As for me, I think they are overused - like many new
toys - and the older map/filter/reduce are often clearer
constructs, but in the other places, where they really
are useful I am starting to use them and grudgingly like
them.... I just don't find the

syntax scans well in my brain...

It may be so. Or maybe we give them integral calculus sooner
to compensate - around the same time as set builder notation...
