[Oberon] Class Methods Vs. Procedure variables in Records

[Srinivas Nayak]

Hmmm...

Richard has a point...
What are the ETH thoughts about it?

Is it because, since we have different applications here, Edit and Draw; hence
different Store commands? Most likely...

It seems good, to have one Store command.
But shall we unify everything on a GUI machinery?
Shall we imagine only one Save button on a Windows desktop, which will save
any kind of file opened on any application, finding the actual application
object from the active window?

I think this will be the extreme use of OO...
But to be frank, this is also not rare...
Now a days most IDEs are like this, example Visual Studio.
This may be handling dozens or more kind of documents and having only one
Save button hanging from File->Save. :-D


With thanks and best regards,

Yours sincerely,
Srinivas Nayak
