Afritssmiðurinn tekur inn óbreytanlega tilvísuna á hlut,
t.d. "Cat (const Cat & rhs)". Við getum því ekki breytt
gildum breyta í tilvísunarhlutnum (nema það sé leyft með
því að breyturnar séu "public", sem er frekar óalgengt).
Ef orðið "const" væri ekki í viðfanginu þá væri hægt að
gera þetta sem þú ert að tala um.
