Back when I gave Eiffel a serious try, I easily slid into [the
equivalent of]:
itsAtom = Atom()
[for an instance member variable -- anAtom for a local,
theirAtom for a class-variable, etc -- Robert Martin's idea
to distinguish those lexically in languages which confuse
the scopes]. In other words, naming a basically-anonimous
"generic instance of class Atom" hardly requires a case
sensitive language, IMHO.
