It just means that the progamming language concept in question has the
same "shape" (i.e. roughly the same syntax) as an English language
syntactic construct in common use. So for list comprehensions we have
[ f(x) for x in l ]
"Make a list of f(x) for each x in the list l."
You can see how the elements of the list comprehension fit sequentially
into the English sentence. As other people have pointed out, this
particular example really comes from the mathematical notation for
f(x) ∀ x ∊ l
...but it's no accident that they both "translate" straightforwardly
