### Code of Conduct

"""Double backslashes within jinja2 expressions
    A user may enter something like this in a playbook::
      debug:
        msg: "Test Case 1\\3; {{ test1_name | regex_replace('^(.*)_name$', '\\1')}}"
    The string inside of the {{ gets interpreted multiple times First by yaml.
    Then by python.  And finally by jinja2 as part of it's variable.  Because
    it is processed by both python and jinja2, the backslash escaped
    characters get unescaped twice.  This means that we'd normally have to use
    four backslashes to escape that.  This is painful for playbook authors as
    they have to remember different rules for inside vs outside of a jinja2
    expression (The backslashes outside of the "{{ }}" only get processed by
    yaml and python.  So they only need to be escaped once).  The following
    code fixes this by automatically performing the extra quoting of
    backslashes inside of a jinja2 expression.
