Again, the point is that out parameters aren't necessary. You and
others may see a lot of them in your code. IMHO, without seeing the
rationale behind the decision, the code you see is messy because of the
out parameters. I also think this is why you're having such a hard time
tracking down variable changes.
For example:
double d = sqrt( x );
is much easier to comprehend than:
sqrt( x, d );
You seem to want to band-aid the latter with:
sqrt( in( x ), out( d ) );
which will, indeed make it a little clearer, but I think it's still not
better than the former.
