Research direction

The issue lacks a detailed description. A newcomer should first read the existing comments (if any) to understand the desired constraints. Then, explore the bayeslite codebase, particularly the constraint definition and parsing modules (e.g., bql parser, model expression). Investigate how current constraints like 'UNIQUE' or 'NOT NULL' are implemented. Finally, open a discussion with maintainers to clarify the syntax and semantics for new constraints such as 'expected lifetime > 0'.
