# This is an augmented version of the original `insert!'. In addition to the
# original functionality, it allows for specifying:
#
# - :trigger_validation:  whether to trigger validation after the record has
#                         been instantiated. Default: false.
#
# - :inhibit_callbacks:   whether to inhibit callbacks supposed to be triggered
#                         after validation. Default: true.
#
# Also, now, any attribute can be assigned, regardless of their being declared
