044 source block with branches

// TEST: Parser acceptance of Source block with args AND branch continuations
//
// This tests that the PARSER correctly accepts:
//   ~event(arg: value) {
//       source content
//   }
//   | branch |> ...
//
// The transform doesn't need to work - we just verify parsing.

import std/io

// Use print.blk which we KNOW works, as baseline
std/io:print.blk {
    Hello, World!
}

// If we can get here without parse errors, the basic syntax works.
// The sqlite3:query case that needs args is tested separately in koru-libs.
