# if with warnings). Here is how I envision things should actually be. Also
# note that a lot of the deprecation can be started today (i.e. the switch
# from get_from_storage to copy_from_storage). So:
#
# $row->discard_changes =>
#   warning, and delegation to reload_from_storage
#
# $row->reload_from_storage =>
#   does what discard changes did in 0.08 - issues a query to the db
#   and repopulates all column slots, regardless of dirty states etc.
#
# $row->revert_changes =>
#   does what discard_changes should have done initially (before it became
#   a dual-purpose call). In order to make this work we will have to
#   augment $row to carry its own initial-state, much like svn has a
