So?  Hasn't that been available since 1974 in the ML [1] programming
language?  Or was that added for the upgrade in 1997?  I admit I've
only read /The Definition of Standard ML (Revised Edition)/ (1997) and
not the original from 1974.

You're not gaining any /internet points/ by trying to pretend something
was invented by Guido van Rossum!


[1] Unrelated to /machine learning/, it's the /meta language/ of Edin-
burg.
