This will require ✨Semantic Analysis✨

Essentially, the parsed AST will have to be visited by a semantic analyzer, before it is passed to the interpreter.

This semantic analyzer should do 2 things:

  • Detect any presence of return statements outside of a function
  • Detect any presence of break or continue outside of a loop

In both cases, we should raise a SyntaxError.
