[UnitaryIron]

Task

Enhance error handling in the Jam interpreter to provide clearer, more descriptive error messages.

Goal

• The line number (if possible)
• A helpful description of the issue

Suggested Approach

• Review places in the interpreter where exceptions are raised.
• Wrap error-prone blocks with try/except and provide detailed error messages.
• Standardize error outputs for consistency.

Requirements

• Knowledge of Python exception handling.
• Understanding of interpreter structure.

Difficulty

Intermediate

Bonus

• Add unit tests that deliberately trigger these errors to ensure messages are clear.
