Practical coding
Over the past week, I've had several reasons to think about Smalltalk.

From code-samples written in Ruby to my thoughts on Object Protocols as I rewrite a significant body of Python into Java.

Variable names changed for obvious reasons :-)
In Python

anotherSubset = [ x for x in state.masterListOfPeople if x not in state.subsetOfPeople ]

Compare with the Java...

ArrayList anotherSubset = new ArrayList();

for (Iterator i = state.getMasterListOfPeople().iterator(); i.hasNext(); ) {

    PersonState child = (PersonState)i.next();

    if (!state.getSubsetOfPeople().contains(child)) {

        listOfPeople.add(child);

    }

}

or in Smalltalk

anotherSubset := masterListOfPeople reject: [: child | state subsetOfPeople contains: child ]

Smalltalk being the probably the most elegant...admittedly you have to know the Collection class inside and out...
