I'm not sure I fully understand your question.

But Dictionaries expect its elements to respond to #key/#value messages, and in the case of Pharo Dictionary is tightly bound to the Association class (and the #-> selector), so there is no way to subclassify Dictionary and specify the class of its elements.

Otherwise you could subclassify Dictionary and have its elements to be instances of "MinipediaLanguage",��that is polymorphic with Association but have language/titles instead of key/value.

I don't see the need for it, though.

Hi,

As some of you may know, I'm a "savage coder" who learned
Smalltalk/Pharo by himself, of course thanks to communities, books and
videos, but without formal training or peers in the same country and
guided mostly by necessity. All this to say that this maybe kind of a
silly question.

Anyway, we have this project called Minipedia[1], that imports Wikipedia
articles and their history. A Minipedia language there, is just a
dictionary, where the key is the language two letters code and the value
for each key is an array of article titles. There is any way to
specialize a Dictionary to tell it, name your 'key' as language and your
'value' as 'titles'?
