• Looked inside the stdlib branch but after a few tryouts decided to postpone it: not much clear was there.
• Continued with researching and cleaning our codebase (PR). Looks like now I finally understand our current testing workflow pretty good (for each test: take the test file, split it to multiple files in a temp dir but looks like most tests have a single file after split too, compile them including libraries to py in our testData dir, run it and check the result).
• More researching, starting from the CLI tool. Also would be good to understand how libraries are taken into the compilation.
