Discussion
20 comments analyzed.
Competitors mentioned: SQL query planning, GraphQL query complexity metering, Ethereum EVM gas mechanism, Zig/LISP metaprogramming
Concerns raised: Homepage doesn't clearly explain Turing completeness guarantees, Turing completeness alone doesn't guarantee cost bounds, Complexity in production use cases may exceed CEL's capabilities, Runtime parsing overhead for user-provided configs, Halting problem with arbitrary CEL programs
Feature requests: Type system with compile-time constraint validation (e.g., type MyType { field: string where size > 8 }), Path expressions for access control, Static analysis to reject filters exceeding performance thresholds, First-class cost estimation/metering for expressions

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
