# Simple access to session.flash.
#
# Flash is a mechanism using sessions to provide a rotating holder of
# key/value pairs.
#
# Every request that is made will rotate one step, dropping contents stored
# two requests ago.
#
# The purpose of this class is to provide an easy way of setting/retrieving
# from the current flash.
#
# Flash is a way to keep a temporary pairs of keys and values for the duration
# of two requests, the current and following.
#
# Very vague Example:
#
# On the first request, for example on registering:
#
# flash[:error] = "You should reconsider your username, it's taken already"
# redirect r(:register)
#
# This is the request from the redirect:
#
# do_stuff if flash[:error]
#
# On the request after this, flash[:error] is gone.
module Flash
# Just for convenience
def flash
session.flash
