Pull request overview
Refactors standard library native-function registration by introducing an Environment::define_native helper and updating stdlib modules to use it, reducing repeated boilerplate in module registration.
Changes:
- Added
Environment::define_nativehelper for registeringValue::NativeFunction. - Updated stdlib module registration functions to call
env.define_native(...)instead of manually constructingValue::NativeFunction. - Removed repetitive
let _ = env.define(...)patterns throughout stdlib registration code.

define_native currently discards the Result from define, so if a native name is already defined (in current or parent scope) registration will silently fail and the function may be missing at runtime. The PR description indicates this should unwrap()/fail fast; consider either (a) returning Result<(), String> from define_native and handling it at call sites, or (b) calling .expect(...) here so duplicate registrations are surfaced immediately.

92-101: Silent error handling is acceptable for native registration, but consider adding a debug assertion.The
let _ = self.define(...)pattern intentionally discards definition errors, matching the previous behavior wherelet _ = env.define(...)was used at each call site. Since native functions are registered at startup into a fresh global environment with no parent scope, duplicate/shadowing errors are not expected in production.However, if two stdlib modules accidentally register the same function name, this would fail silently. Consider adding a
debug_assert!to catch such mistakes during development:🔧 Optional: Add debug assertion for duplicate detection
pub fn define_native( &mut self, name: &'static str, func: crate::interpreter::value::NativeFunction, ) { - let _ = self.define( + let result = self.define( name, crate::interpreter::value::Value::NativeFunction(name, func), ); + debug_assert!(result.is_ok(), "Native function '{}' already defined", name); }🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed. In `@src/interpreter/environment.rs` around lines 92 - 101, In define_native, currently the result of self.define(...) is ignored which hides duplicate registration errors; update define_native (the method name) to capture the Result from self.define(name, Value::NativeFunction(...)) and add a debug_assert! that the result is Ok (or that Err matches duplicate/shadowing) so development builds will panic if two stdlib modules register the same name; keep the original behavior in release builds by only using debug_assert! and do not change the public API of define or Value::NativeFunction.
