Last night we (Maik, Paul, Luca and me) had an interesting talk on "variable classes". Many scripting languages allow to change the structure of a class, and doing so, changing the runtime structure of the instances they have generated. Although this is generally regarded as "horror" in terms of object oriented programming, and relying on this is considered a bad practice, Maik and Paul (exp. Paul) convinced me that the thing has "a meaning" when profiling the an application at design/setup time.

Also, if specifically constrained and shaped down with the help of well-defined language extensions, as the type contracts we're designing, altering a class may not be as bad as it sounds.
