The current implementation is quite basic and there's room to make it better. Following are few ideas which could be explored.

• Test edge and special cases
• Implement tests for pieces whose logic is complex
• Test IO functionality
• Test for variables: defining, set, get inside an env
• quick check tests

Effectively, the tests should be able to catch bugs such as #3 and help in developing features like #4 as way to do TDD

The current implementation is not exactly a cli but more like an executable. It would be good to have cli options/flags for version, help, reading a file etc.

When writing s-expressions having trailing spaces inside parens, the interpreter gives parse error.

This issue was tried earlier but did not make a lot of progress instead injected new errors into defining functions etc

The current implementation of importing standard libraries or .scm files does not work.

(load "stdlib.scm")

results in an error.
One of the possible reason could be incorrect file path but there's more to it
