Historical research and curiosity Q: What ever happened to #bitAt:put:

Hi all,

As a bug tracker, I sometimes get into the mood for historical research. What happened 30 years ago and how does it affect us now?

So with my faithful mischief maker puck looking over my shoulder I have been reading the Draft Ansi Smalltalk Standard.

I mention puck because when we don't recognize something he suggests ways to try things out. Doing so we found that

15 bitAt: 1 "works and returns 1"

yet

15 bitAt: 1 put 0 "is not understood, It brings up a spelling corrector."

So I'm stumped.

Does squeak differ from the standard by not implementing bitAt:put:

Did the selector not make it in to the final standard?

How do the other major smalltalks ( Cincom, Gemstone, Newspeak) compare in the implementation of #bitAt:put: ?

Yours in curiosity and service, --Jerome Peace

Even #bitAt: seems to be a very recent addition. It's not in 3.8.

And it's not even clear what #bitAt:put: should do on SmallIntegers, which are immutable. What does the standard say?
