PS: *Neither* #flattened nor #flatCollect: can be blamed on
40 years of history. #flatten(ed) arrived in Squeak back in
2015, at which time #flatCollect: did not exist. In fact
there is *still* no #flatCollect: in Squeak, although Squeak
does have #gather:, since 2002.

"Flattening" is problematic in every programming language I know
that has something like it in its library. It was born
problematic in Lisp and it has continued problematic ever since.
(I am aware of several Smalltalk systems offering it. With the
exception of Squeak and Pharo, no two of them agr
Hi Kasper,
Thanks for your reply!

Interesting. So I double-checked - and found that the "flatten" in my

10,
