I'd still rather the exact wording isn't in code, personally:

    get_msg('fail_add_address')

vs.

    'I\'m sorry, we\'ve been unable to add the address %s at this time,' \
    ' please try again later.'

(... but that's an ideal I have without ever having worked with it, so what do I know, and ymmv, etc.)
