I am trying this for various issues, too.

The requested changes need just a bit more work. I hope that coding efforts can
be saved after corresponding adjustments.
Other tools like approaches for static source code analysis can also help to
identify update candidates.

I would be more careful with the use of such an ambiguous and fuzzy term where
software developers prefer strict programming rules.

Return code checking is a cross-cutting concern like several other design
patterns that are scattered around in the source code base.

The main point is to specify in a single source file which advices should be
applied to a lot of function calls. The traditional attempt to cope with this
situation is to create wrapper libraries.

No - I hope that more participants can be convinced of the benefits and the
applicability in multidimensional software design.

I see it as a move from manual application of patterns to an automated weaving
step during the build process.
