Keeping the code wrong and adding a bizarre workaround is "twisting the

In many respects, they have pushed Smalltalk to do things that, I think,

Is there a way force allSubclasses to implement the method?
No. Pretty much, you need to avoid subclassing concrete classes.
i.e. if A has subclasses B and C, refactor to create an abstract A' and move
A to be a leaf subclass of A'.

The reality is that the browser presents either the class' behaviours or

show you this.
Another way to determine this is to look at the code and think about where
the sending method is implemented and where the invoked method is
implemented (assuming that there really is one).

Perhaps you should start by looking to see whether there is or are classes

in the singular form).

Let's start with the size of the diamond (it field, actually). In the

I've found this topic both interesting and upsetting at times. I do
understand the desire to address Pharo issues without getting sidetracked
by other topics.
However, this particular thread started as a Pharo user's success story.
Didn't it? Isn't Pharo the implementation used for the contest? Ar

Thank you, Richard.
Would you be kind enough to annotate the GemStone link to point out that we
have a free license that permits commercial use, not only personal use.
Thanks again for all your hard work!

A feature request is often a description of a problem from a single
perspective. Learning to recognize whether it is one or the other will be
crucial to your long-term success as a programmer.

Paul, I'm going by memory and not Pharo specific.
I believe the default handling of the end of the exception block is
implicitly equivalent to ex return: nil.
So, to get further handling of the exception, you need to #pass it or
otherwise resignal it. Then the development environment will catch a

Samuel,
One thing I don't recall seeing in this thread is a discussion of the

I find it helpful to consider #asWhatever to be a conversion method, used
to convert one object to another essentially compatible class. e.g.
#asFloat sent to an integer would be expected
Thanks for sharing that, Peter. It's an important point.

I don't know the correct answer, but I am skeptical of one that relies on a
specific implementation rather than a specific definition.
I would like to see and understand the arguments for one interpretation
versus another.
Prima facie, the expectation that set behaviour propagates through the

Thank you, Renaud, for explaining that. I am so glad to see that Pharo has
addressed this and made it so simple. I've seen too many UIs that fail on
this kind of thing.
Kudos to those people who created this. You nailed it!
