# perf fixes, review for each rails upgrade.
# This speeds up calls to present? and blank? on model instances
# Eg: Topic.new.blank? (which is always false) and so on.
#
# Per: https://gist.github.com/SamSaffron/c8bbc8c7b6bf3b0148760c887df18b55
# Comparison:
# fast present: 25253295.0 i/s
# fast present 2: 24623199.7 i/s - same-ish: difference falls within error
# slow present: 335003.0 i/s - 75.38x slower
# slow present 2: 275212.8 i/s - 91.76x slower
#
# raised with rails at: https://github.com/rails/rails/issues/35059
