Hi Oyvind,

Correct me if I'm wrong, but isn't an object a data structure in disguise,
and a method a procedure call in disguise? And isn't an API a procedure
library? I don't know Simula, but all the OO stuff I have ever seen just
seems to be data structures and related procedure/function libraries, plus
long lists of restrictions on their use and relatedness trees among the
structures based on shaky metaphor.
