Hi,
I'd like to draw your attention to something else: consistency.
I remember the days when Cincom added Namespaces to classes and the
class definition template changed drastically. It took me quite a while
to get used to that.
And there is this other aspect in the consistency field: most Smalltalk
literature will include and address that line. If you learn Smalltalk,
such small differences can cause trouble.
And what if I need PoolDictionaries? How hard will it be to find the
place to add my reference to them?
A fair amount of Pharo code may not make much use of PoolDictionaries,
but other dialects do. I know Pharo has the concept of "never look back"
and it is good to be prepared to cut off old strings. But there is a
price to it.
Seaside, apart from being a great web framework, has achieved something
that was excellent and helped the whole Smalltalk universe make a leap
forward: all Smalltalk dialects moved closer together and honestly
worked on being more compatible. Suggestions like this may not break
much of this per se, but many such cracks make a wide canyon. I find the
argument that a certain line of code may irritate students a bit weak.
It may make their life harder once they read code from other dialects.
Should we remove class browsers because students are used to use text
editors?
Just my 2 cents

Hi all,
I am preparing slides for a course. I came to the typical:
Number subclass: #Complex
instanceVariableNames: 'real imaginary'
classVariableNames: ''
poolDictionaries: ''
category: 'ComplexNumbers'
Which made me think: Who uses poolDictionaries? I suspect extremely few of us.
Why not add this to Class:
Class>>subclass: aSymbol instanceVariableNames: instVarNames
classVariableNames: classVarNames category: aSymbol
^self subclass: aSymbol
instanceVariableNames: instVarNames
classVariableNames: classVarNames
poolDictionaries: ''
category: aSymbol
And have the new class template as follows?
Object subclass: #NameOfSubclass
instanceVariableNames: ''
classVariableNames: ''
category: 'Kernel-Classes'
It would be a bit cleaner. I know us old timers don't even see the
poolDictionaries: line anymore, but I dislike having to explain it to students.
