filter is a grep that reads. It keeps each record where the answer is yes and passes it through unchanged.

The lesson

Six of the seven songs at 0.7 are on Abbey Road. A Day in the Life came out on Sgt. Pepper's Lonely Hearts Club Band. At 0.9, Octopus's Garden and Something drop out. A Day in the Life stays.

A higher bar cannot remove a mistake Jev is sure of.
