Workers RPC now works across Python and JavaScript

Cloudflare announced that Workers RPC can now operate across Python and JavaScript Workers. Developers can call methods implemented in a Python Worker from a JavaScript Worker, and vice versa, without defining schemas or adding dependencies. Objects can be shared across the two languages, including calling methods on Python objects from TypeScript. The feature extends Workers RPC, introduced two years ago on Cap’n Proto RPC, and follows last year’s browser-to-server work through Cap’n Web.
