IAANM, Church didn't choose lambda at all. He chose to put a "hat"
(like a circumflex accent) above the bound name. Then, because of some
typesetting difficulties, this was transformed into the nearest thing
that looked like it: a capital lambda in front of the name ... and
later the capital lambda turned into a lowercase one.
