Yes, that is a good write up, touching on all kinds of aspects, balanced too.
Pretty complicated subject, right ? ;-)
As you mention it is quite hard to reach an agreement.
Objectives/goals are different for everybody.

Yes, a good read as well.

Since we had those discussions long ago, I've actually grown quite used to writing

{ #foo->1. #bar->2 } asDictionary

I know it is not super efficient, or super compact, but I can certainly live with it.

I know. But I was a bit sad, when porting SmaCC from Dolphin to Pharo, to have to remove all the literals optimisations John Brant has added in the code generation, such as:

^ [ Dictionary new at: #foo put: #a; at: #bar put: #b; yourself ] once [1]

and:

##(Character value: 16rXXXX) [2]

(I have a framework of thought where it would be possible, for the pharo compiler, to track and optimise such methods as [1] without requiring the "once" above, but I have no idea if the gain would be worth the pain)
