i think that we are basically all agree on what we mean...
however, matju tries to be exact when it comes to definitions. calling 
messages with an selector that is not defined as a standard a "undefined 
set" is not correct in a mathematical sense (were mathieu seems to spend 
some time; i believe him)
i think that we should get terms right if we want to define a consistent 
programming language.
i also think that mathieu's objections are funny and should be taken 
with a grain of salt (i enjoy his objections, so i try to not be offensive)
