I was thinking about list comprehension, which is what
programming on ranges is. Isn't it?
list is a good term, but it's already taken. so naming
range as
list will create unnecessary confusion. alas. yet набор is
short
and easy, and it's not widely used, as set is translated as
множество.

I don't yet see a word which clicks in this case, but we got
multiple reasonable suggestions here. Perhaps I'll be fine with
one of them.

As I see it, there is no constructor in your class with a double

Hi,
I was just refactoring a project to compile under 2.067.
The fixes themselves were trivial: just adding import
std.traits; to some files. Apparently its pieces were publicly
imported by another module in 2.066. So, it's the right fix
anyway.
Understanding what happened, however, took
