Re: [squeak-dev] Renaming "Squeak"

John Thornborrow
Why not just implement your own #asDictionary message on
SequencableCollection, if it's that much of an issue?

asDictionary
        "Answer a Dictionary with receivers elements.
        Assumes all elements are associations"
        | dict |
        dict := Dictionary new.
        self do: [:each | dict add: each].
        ^dict

That will do what you're asking.

John.

John: that was not the question at all ;)

Folks: if you continue this thread, can you *please* rename it  
appropriately?

Thanks,

You misunderstand me.  You have the parser code in your image and you
can modify it.  I meant that there is probably a "standard" way to do
it in many of the Smalltalks.  Though in Dolphin it isn't needed since
they already have macros (the ## syntax).

Well, you are applying the "verbose" label to something different then
I am.  Personally I prefer the keyword arguments and actually find it
concise and self documenting.  By verbose I meant "how many lines of
code to do something" and "how much of this code is just silly
boiler-plate that I just don't have a way to avoid".

I used to have a link of a study comparing Java, C++ and Smalltalk.
At that time Java was 3 times more productive then C++ and Smalltalk 3
times more productive then Java, based on how much code the developer
had to write.
