I agree there was not a consensus reached on this issue. But I
also feel all the arguments were fairly represented, and it was
time to make a decision.
Note that either the decision is to reserve attribution to
special types, and it is rather safe as it is what is done in
other languages, or it is to allow everything to be an attribute,
and it should be field tested before going into the main release,
because unless I'm mistaken, no language do that ATM, so we can't
rely on previous experience on the subject.
