226 for each reverse each refused

✓ Passing Passing: the compiler rejects this program as expected.

Code

~import std/io

// `! each` and `! reverse-each` are alternative delivery axes of one call —
// attaching both means the call describes two traversals, which is refused:
// a single `for` call is a single traversal. Pick an axis.

~for(1..5)
! each i |> std/io:print.ln("{{ i:d }}")
! reverse-each i |> std/io:print.ln("{{ i:d }}")

Actual compiler output
