<div>I agree that the behavior you propose is not
problematic per se.
<p>But, as I mentioned, it brings up can of worms. For
instance, now a superclass constructor could see its
field with a non-zero value. Which could definitively be
surprising. After all, there might be code in the wild
assuming that an int field that has not been assigned
yet has value zero - whether writing code like that is
good or bad, it's a separate question. My point here is
that here you cross a fine line between "let's make the
language more expressive" and "this change might have
some compatibility impact".<br>

<div>Yes, but for this to happen the subclass would have to be
in effect intentionally subverting the superclass
constructor.<br>

<div>In other words, a problem like you describe can't
suddenly just start happening "by accident" just because
this new feature exists...</div>

<p>Well, you could have a subclass (in some client jar) which
"subverts" as you say, some superclass in a library. Perhaps the
library was not prepared for that kind of behavior, and now
there's a new bug.</p>
<p>IMHO, we should try to stay well clear of that can of worms. It's
not like we have to open it now either - the other things you
propose are 100% non-controversial.</p>
