Thanks a lot, Ben, for your remarks; I applied them all. I am glad you liked the article. Sven

I wrote another article:

Tiny, yet so beautiful The smallest piece of great Pharo code https://medium.com/concerning-pharo/tiny-yet-so-beautiful-1ef5149c910e

I love reading these articles of yours. Very well written. Feedback for some minor wordsmithing...

- 2 out of 5 reserved words in the language.) + 2 out of _the_ 5 reserved words in the language.) _They are instances respectively of classes True and False, that have common superclass Boolean._

"Nice article. But asBit has existed in @SqueakSmalltalk since at least 2004. Why not say so?" https://twitter.com/bertfreudenberg/status/707922868273856512 <https://twitter.com/bertfreudenberg/status/707922868273856512>

And indeed, in Pharo I see it added on 27.3. and 28.12.2012 (why almost a year difference?)

And in Squeak I see it added 1.7.2004 (although they don't have it in Boolean class).

The rest of the Boolean class looks pretty identical to the letter (including comments), so it makes one wonder why wasn't this copied over.

It was, the same version of asBit you find in Squeak was present in Pharo 1.4 and earlier. Though, uncategorized, and without the subclassResponsibility implementation on Boolean. 2.0 development was hectic, hard to tell if it was cleaned away and then re-added/invented ( I think it may have, I seem to remember it being an extension in NB for awhile) The source compaction that happened at 2.0 release removed any lingering traces of the old version, either way attributing Anthony Hannan as well wouldn't be entirely out of place. Either way, a beautiful bit of code! Cheers, Henry

"Pharo forked in 2008, that is a long time ago. Get over it. We are not
looking backwards, we are looking forwards."

Yeah who cares ? Afterall Squeak only made Pharo possible. No big deal,
lets look forward. Pharo is not Smalltalk and is not Squeak, its back from
the future.
