Some recherche regarding the requirements and conditions of the GPL
made it clear that we are obliged to have at least an summary statement
of all authors and the years of their contributions embedded somewhere
in the source itself. The Git history alone is not sufficient to fulfil
this requirement, since a code base could be packaged as Tarball
and passed-on outside of any Git repository.
Thus I propose the following policy
- add yourself to the copyright header whenever you made
some ''significant'' contribution to a code file
- maintain a list of relevant authors at top-level,
indicating a time range of their contribution
- use the same information also in the debian/copyright (DEB package)
- clarify in the LICENSE that authorship can be extracted from Git
__Remark__: Anton Yakovlev made a single code contribution in 2009 (87e528bd),
which was never used anywhere and removed as part of a general clean-up in 2023.
Thus I do not list him as a code author, but he is mentioned in credits.txt
- use a current copy of the GPL2 text, downloaded from fsf.org
- reformat the AUTHORS and get rid of the table formatting
- Stackoverflow has upgraded its Subscriber Content license to CC-By-SA 4.0
The actual trick to make it work is to use decltype on the function operator

In addition, we now pick up the functor by template type and
store it under that very type. For one, this cuts the size
of the generated class by a factor of two. And it gives the
compiler the ability to inline a closure as much as is possible,
especially when the created Binder / Mutator lives in the same
reference frame the closure taps into.
