I’ll echo @LostKobrakai’s sentiment - the originally proposed is a solution to a problem I don’t have, and will only result in less-readable code and more lessons needed for getting developers without prior Elixir experience up to speed (which is already a problem).
Having two ways of doing something adds an additional layer of cognitive burden to a developer, as now there isn’t just the coming up with the solution, there is the added task of deciding which solution is best.
The acc/rebind mention ideas are interesting, but I’d much rather it work without the internal assignment, maybe something along the lines of:
i = 0
{list, j} = for element <- [1, 2, 3] do
element * i
acc
i + 1
result
i
end
list #=> [0, 2, 6]
i #=> 0
j #=> 3
Or even just
i = 0
{list, j} = for element <- [1, 2, 3] do
element * i
acc
i + 1
end
¯\_(ツ)_/¯
If it was only 1 special symbol it would look a lot better. I would love
