[Oberon] Message Objects in Oberon

[Srinivas Nayak]

Dear All,

Oberon OS source code uses Handlers and Message objects extensively.
We know, they are costly (run time type check),
unhandled messages consume more time even (sequential check of if else ladder),
compilers can't catch the errors made (inappropriate message sent to an object).
Still how do we consciously decide to use message objects more in Oberon (which benefits outweigh all these)?



With thanks and best regards,

Yours sincerely,
Srinivas Nayak
