Unofficial Bash Strict Mode

Sometimes a programming language has a "strict mode" to restrict unsafe constructs. E.g., Perl has use strict, Javascript has "use strict", and Visual Basic has Option Strict. But what about bash? Well, bash doesn't have a strict mode as such, but it does have an unofficial strict mode:

set -euo pipefail

set -e

class TTLDict(dict):
    """ A dictionary with keys having specific time to live """

    def __init__(self, ttl=5):
        self._ttl = ttl
        # Internal key mapping keys of _d
        # to times of access

The State design pattern.

In Python this is done dynamically by changing the __class__ attribute.
