This commit introduces two main changes:
1. **Binder Refactoring**: The `Binder` has been refactored to support
recursive definitions by pre-declaring names in the scope before
binding their values. This ensures that a name is visible to itself
when its definition is being processed.
2. **Stdlib Operator Implementation**: Several standard library
operators, including `+`, `-`, `*`, `/`, `>`, and `<`, have been
implemented. These operators now correctly handle both `Int` and
`Float` types for numerical operations and comparisons.
Additionally, the display formatting for `Value::List` and
`Value::Record` has been improved for better readability. The
default source code in `main.rs` has also been updated to include a
Fibonacci example, demonstrating the new recursive capabilities.
