Yeah, but I used the wrong word "features", which typically means "end
user features".
Instead, I had in mind "developer features", i.e. core features that
will be called later
in "client" code (I am in a framework mindset here).

Typically I start with a small class, then the class becomes larger as
I add features that will
be useful for client code, then I discover than the class has become
difficult to mantain.
So I cut the features and and I implement them outside the class and
the class becomes
short again.

However, I *cannot* know from the beginning what is the minimal set of
features
needed to make short the client code until I write a lot of client
code. I can make things short
only after I have made things long. I think this applies to me, to you,
to Pascal and to
everybody in general. It is impossible to start from the beginning with
the short program,
unless you already know the solution (that means, you have already
written the long
version in the past). Still, some naive people think there is a silver
bullet or an easy way
to avoid the hard work. They are naive ;)
