Arlo Guthrie and the origins of the Collection protocol

A bit of history to make you smile:

Rick DeNatale at Talk Like a Duck writes about
How Arlo got injected into Ruby [via Smalltalk].

During the interview he [Dan Ingalls] was asked about the origin of those enumeration methods of the Smalltalk collection classes. Alan Kay had told the interviewer that they had come from a song. At first Dan didn’t remember this but then remembered that there was a song which had a string of words like inject, select, detect etc. As far as I recall, though he didn’t name the song.

But I recognized it right away, here’s how “Alice’s Restaurant Massacree” transitions from the littering trial to the draft:

Came to talk about the draft. They got a building down New York City, it’s called Whitehall Street, where you walk in, you get injected, inspected, detected, infected, neglected and selected.

So that’s how the enumeration method names came into Smalltalk (and, later on, into Ruby)!
