The `GlobalStore` was refactored to clearly distinguish between
immutable RTL values and mutable user-defined global slots.
The `Environment` struct now holds:
- `rtl_values`: An immutable `Rc<[Value]>` for pre-defined RTL values.
- `user_values`: An `Rc<RefCell<Vec<Value>>>` for user-defined mutable
globals.
The `GlobalStore` struct now takes both `rtl` and `user` as parameters
and uses `rtl_len` to determine which store to access. This change
separates concerns and better reflects the immutability of RTL values
after the bootstrap phase, aligning with the project's concurrency
rules.
Documentation in `docs/Analysis_Environment.md` was updated to reflect
these structural changes.
The `instantiate` method in `Environment` has been refactored to return
`Result<Rc<Closure>, String>` instead of `Rc<NativeFunction>`. This
change separates the creation of a `Closure` from its execution,
allowing the caller to manage the `VM` lifecycle and choose the
appropriate execution strategy (e.g., single run vs. repeated benchmark
iterations).
The `NativeFunction` type is now exclusively used for true Rust
intrinsics. The benchmark runner has also been updated to reuse a single
`VM` across iterations, improving performance by avoiding repeated VM
allocations.
The `dump_ast` method previously bypassed the `compile` method, which
meant it would silently ignore parsing errors. This commit ensures that
`dump_ast` now delegates to `compile` and correctly propagates any
parsing errors. This aligns the behavior of `dump_ast` with other
compilation steps and provides better feedback to the user.
Fix: Dump AST ignores parse errors
The `dump_ast` method now delegates to `compile(source).into_result()?`
to properly handle and report parse errors, ensuring consistency with
the compilation process.
