This PR introduces the "SurrealQL: Revised Control Flow" RFC.

Rendered

RFC Summary

The current state of control flow in SurrealQL is quite convoluted.
Complex queries are subject to excessive nesting, transactions are subject to leaking phantom states, and transactions cannot be nested.

This RFC proposes changes to SurrealQL to improve usability in complex queries while still maintaining flexibility to write simple queries:

  • Make RETURN statements break execution.
  • Introduce block expressions.
  • Change the semantics for transactions to allow for greater usability.
  • Make RETURN semantics more consistent.
