You can use v:val in map()/filter()

I also think this is a problem.. but can't think of any good way to solve
it. My best guess is to add a new scriptversion which would require the
lambda to take exactly two arguments. But this won't catch simply swapping
idx and val by accident.

I think this is a design mistake:
:echo map([1, 2, 3], {idx, val -> val + 1})
It should be
:echo map([1, 2, 3], {val, idx -> val + 1})
95% of map() expressions do not need v:key (er, idx).
It annoys me whenever I use it.
Especially nice: dummy examples that are
