ssair: another bug
```
julia> iterate(t::Tuple, i=1) = (i > length(t) ? nothing : (t[i], i+1))
julia> function any_iterate(f, y)
st = iterate(y)
while !(st === nothing)
f(st[1]) && return true
st = iterate(y, st[2])
end
return false
end
julia> code_typed(any_iterate, typeof((x -> :c == x, (:a, :b))))
```
