No, currently OpenC++ does not implement arguments to declaration
modifiers.

OpenC++ can be extended to be whatever you want it to be, provided that
you do it by yourself or find resources to do it. OpenC++ is maintained by
a group of volunteers who are busy earning their salaries or university
degrees and usually can spare only a little time for OpenC++.

Technically it should be possible. However we do not want introduce
changes that break backward compatibility (if the feature you are
requesting has to do it, it perhaps should be activated only on user's
demand).

Probably not. Depends on what you mean by "hard". I could perhaps give
more accurate answer if you supply e.g. examples of what you would like
in OpenC++.

OpenC++ was implemented many years before C# was designed.

What is "abstract programmer"?
