Thanks. I know it takes guts to publicly admit that over time your
own creation has become less ideal than you wish it to be, but it
needed to be said.
Michael, please realize that the only reason people comment on the
patch series is because they care about what the series brings to
us. In other words, your effort is appreciated. For a change that
we want to have in our codebase, the functionality of the code
immediately after the change is applied of course is important, but
the maintainability of the result also matters.
We want to make sure that anybody who wants to understand and
improve the system can read the code without distraction from
inconsistent coding styles used in different sections of code. We
want "git log" (or "git log git-svn.perl perl/") output to tell a
coherent story about how the code evolved and why these changes are
made in a consistent voice to the readers. We want people to be
able to "git log | grep Signed-off-by:" to count the contributors.
A contributor has enough room to be creative in how his or her code
is designed. Updating the code to follow the "convert as early as
possible", and (during subsequent discussion with Eric) suggesting
use of class instances instead of bare strings to make it harder to
mistakenly use bare unconverted strings are two examples you already
showed creativity in areas that matter.
There is no need to be creative in ChangeLog and coding styles; it
only hurts maintainability.
Regarding the operator overloading of "eq" for comparing the
converted strings, I still think it will hurt maintainablity (we
want to make sure that it is harder, not easier, to make wrong
changes to the code in the future), but I may be mistaken and you
may have better ideas. If you can use overloading in such a way
that it won't harm maintainability and yet makes the resulting code
easier to read, I don't have any objection.
What I won't accept is "maintainability does not matter". It does.
