What's this?

use(key = nil, used = true) protected

Used internally by the keep and discard methods

use()               # marks the entire flash as used
use('msg')          # marks the "msg" entry as used
use(nil, false)     # marks the entire flash as unused (keeps it around for one more action)
use('msg', false)   # marks the "msg" entry as unused (keeps it around for one more action)

Returns the single value for the key you asked to be marked (un)used or the FlashHash itself if no key is passed.
