Which are usually under GPL or compatible. GPL has the nice property
that any non-commercial contributer can be sure no one will ever
commercialize his contributions; but still any commercial user can
use it or sell services on top of it, and in case of LGPL even build
products on top of it. My concern as researcher is that BSD does
fully satisfy the interest of non-commercial contributers in the same
way. Maybe that got lost in all the rant with Doru.

Hi Adrian,
I saw that you removed Collection>>separatedBy: from CodeFoo. I
thought this was a nice method, and I looked for other similar
methods to use, but I cannot seem to find the right one.
What am I missing?

Hello,
I am a new mooser, I am working on a Smalltalk project with VisualWorks. I am trying to write a unit test but I have a problem: I have not possibility to run and to step my test because I don't have the tools for it. Nevertheless, I have loaded the package StefFoo, my test class inherites from SUnit.TestCase.
What did I forget to run my tests?

Hey Stef, dear Moosers,
there is a new implementation of lazy (or dynamic, as I call them
now) inst vars for Moose. The new implementation is not based an wide
classes, but on anonymous subclasses, and includes very strict sanity
checks to guarantee type safety and Smalltalk's language model.
You may only extend a base class with an inst var, iff
name isString.
name isSymbol not.
name allSatisfy: #isLetter.
(case allInstVarNames includes: name) not.
class canUnderstand: name asSymbol.
class canUnderstand: (name copyWith: $:) asSymbol.
and you must implement the accessors in the class as follows
class >> foo
^self dynamicInstVarNamed: 'foo'
class >> foo: value
self dynamicInstVarNamed: 'foo' put: value
with this setup, we can guarantee that no tool is broken, neither the
browser, nor inspector and debugger or senders- and implementors-of.
Except for the first write access, access time on an dynamic instance
variable is guaranteed to be the same as for "normal" instance
variables.
Please refer to DynamicInstVars and DynamicInstVarsTest on SCG Store,
for a first draft implementation.
cheers,
AA
You are right.

As ESUG was so inspiring, I could not resist some VW hacking on the
train home...
If you browse to WideClass and WideClassTest on SCG Store, there is a
simple implementation of wide classes. As we have tons of empty inst
vars in moose models, that might help us to save some megas on large
case studies.
How to use it?
Sending #wide:put: to any object will install an instance var and
accessors on the receiver instance.
o := Object new.
o wide: #foo put: 4.
o foo
and even better, if you implement #foo and #foo: as follows
foo ^nil
foo: arg self wide: #foo put: arg
upon first execution of #foo: the foo inst var is installed and both
methods get properly overriden with simple accessors. There is no DNU
hack anywhere!
Hope you have some fun playing around with it!
cheers,
AA
Hi guys
As I mentioned during the moose workshop we would like to get your
evaluation of our ideas.
I would really like if you could perform the experiment described at:
