Overview CastleCode portray

When translating CastleCode into RPy code, a valid RPY identifier is needed for every name (like an ‘ID’) used in the source code. On one hand, this translation should be stable, repeatable & predicable. But at the same time any valid CastleCode should result in a valid RPy (aka python) name – and never in a keyword of the backend.
We call this transformation “to portray”; describe and depict the source-code in an particular way (so that can be used by the (selected) Translator

The Sieve: CastleCode & RPy

In this article we study the well known The Sieve (basic variant).
See that link for the used code: chapter: Castle implementation; Tab: Sieve.
