Grace Introduces Type-Safe Eval And Imports
Grace's language post describes a type-safe eval feature (import read) that uses bidirectional staged type-checking to prevent evaluating code with type errors. The mechanism enables type-safe dynamic imports from GitHub, HTTP, or LLM-generated code (import github/http/prompt) and supports a privacy-protecting prompt workflow where sensitive data never leaves the interpreter. The feature preserves type safety while allowing runtime code composition, though eval still risks untrusted input.
