    If you attempt to steal a variable which does not exist, then a run-time
    exception will be thrown.

WHY YOU SHOULD NOT USE THIS MODULE
    When people declare lexical (`my`) variables within a sub, they (quite
    reasonably) expect these to stay local to the sub. If they rename those
    variables, change them (say replacing a hashref with a hash), drop them or
    whatever, then they don't expect code outside the sub to pay much
    attention.

    Peeking at your caller's lexicals breaks those expectations.

    Peeking at your caller's lexicals leaks an abstraction.

    Peeking at your caller's lexicals can cause spooky action at a distance.
