:=
  if o is Some t return o -> T then fun=> t else False_rect T \o notF.

Use

Each declaration is split into a statement (signature/claim) and a proof (body) that are disjoint and together form the complete declaration, for proof modeling, autoformalization, retrieval, and dependency analysis via deps.
