I agree Philip here !

You are right, and this rule work in 99% of cases I think.
But always exists exceptions.

For example, we develop DBMS, piece of code other developers/users will
tease billions times. But that is other story. We develop weapon. Other use
it.

Okay, this raise another issue:

    do you have on hands ANY research, which prove that
    -- OO layer way is faster for development?
    -- if yes then for which tasks? (unlikely for all, right)

I cannot remember I have read for years any info about this.
So IMHO we talk on terms of "spirit" and "belief" here.

It will be great take some tasks, and see how they can be solved in this and
that way. Then compare results...


Again, we try develop Valentina to be as flexible as possible.
We right now offer to developers SEVERAL ways to go for EACH API we support.
May be we really need take a more deep look in direction you point.


I think it will be great also if you find time to take more close look on
Valentina and its design. Of course if you have time on this ..
