Subject: [PATCH] fix: Bool | Nil cast for sync= on Crystal 1.20.1
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

 returns . Direct assignment
to  with the nilable union fails on Crystal 1.20.1 at the
type-checker level (comparable to issue #8).

Change  →  so the RHS is always
plain , matching what the caller already did before the
partial fix that introduced .
