    Applies evaluation restrictions defined in the context. Currently does not support evaluation of functions with keyword arguments.

    Does not evaluate actions that always have side effects:

    - class definitions (``class sth: ...``)
    - function definitions (``def sth: ...``)
    - variable assignments (``x = 1``)
    - augmented assignments (``x += 1``)
    - deletions (``del x``)

    Does not evaluate operations which do not return values:

    - assertions (``assert x``)
    - pass (``pass``)
    - imports (``import x``)
    - control flow:

        - conditionals (``if x:``) except for ternary IfExp (``a if x else b``)
        - loops (``for`` and `while``)
        - exception handling

    The purpose of this function is to guard against unwanted side-effects;
    it does not give guarantees on protection from malicious code execution.
