034 metatype branch requires binding

○ Planned This feature is planned but not yet implemented.

Failure Output

error[KORU010]: '_' is only legal as the body of a branch handler

    | ^
  hint: '_' has meaning only as `| branch [binding] |> _`. Outside a branch handler body — top-level void chain, split-pipeline tail — `|> _` is meaningless.

Code

// Test: Metatype branches require bindings
// The Transition metatype branch must have a binding (t or _)
// | Transition |> is invalid - should be | Transition t |> or | Transition _ |>

const std = @import("std");

~import std/taps

~tor work {}

~tor logger {}

~proc work|zig {
