    Eval `code` and return a map of variables and their values.

    `code` should be valid Python code.
    Only the builtins `list` and `set` are provided.

    Note: this executes arbitrary Python code.
    Because of the limited builtins list this should be reasonably safe.
    Still only use this with known valid code!
