014 void chaining nested

// Test: Void event chaining with nested continuations
// When chaining void -> event with branches, should parse nested continuations correctly
// Pattern: ~void-event() |> branching-event()
//              | branch1 |> _
//              | branch2 |> _

~tor void-event {}

~tor branching-event {}

// MUST_ERROR: branching-event is declared void (no branches), so `| error` is a
// branch handler on an event that has no branches — category error.
~void-event() |> branching-event()
