Research direction

Start by reviewing the binary format rules for continuation and signature types, together with the existing heap type ordering precedent mentioned in the issue. Determine the required specification changes and how canonicalization of recursive continuation types should be validated; the payload names no files or tests.

Written by the indexing model from the issue text.

Description

I think that without loss of generality we can require (in the binary format) that the definition of continuation types come after the definition of the signature type they reference. This would make a minor simplification in canonicalization of recursive continuation types.

We do have precedent for this in that, for all heap type definitions, we require their supertype definition, if any, to appear before them.
