Was there more recent discussion about switch? I think I missed it, last
thing I am aware of is #5410. And of course see Switch.jl.
In any case, I find the proposed syntax a bit obscure and
complicated. I would prefer using the result of
findfirst(x->input % x == 0,[2,3,5,7])
or if that does not help, then explicit currying,
input = 119
let d(x) = input % x == 0
if d(2)
# code
elseif d(3)
# code
elseif d(5)
# code
elseif d(7)
# code
end
end
Best,
