How about someone starts paying attention to what Don posts?
That

reading
this NG (to be aware of what comes next) and writing (to

personal and Sociomantic concerns) and have literally no idea
what can
be done to make communication more clear.
I don't remember who it was, but I'm pretty sure *somebody* at
Sociomantic has stated clearly their request recently: Please
break our
code *now*, if it helps to fix language design issues, rather
than
later.
More particulars would be definitely welcome. I should add that
Sociomantic has an interesting position: it's a 100% D shop so
interoperability is not a concern for them, and they did their
own GC so GC-related improvements are unlikely to make a large
difference for them. So "C++ and GC" is likely not to be high
priority for them. -- Andrei
Yes and this is exactly why I am that concerned about recent
memory management policy thread. Don has already stated it in his
talks but I will repeat important points:
1) We don't try to avoid GC in any way
2) However it is critical for performance to avoid creating
garbage in a form of new GC roots
3) Worst part of Phobos is not GC allocations but specifically
lot of temporarily garbage allocations
This is a very simple issue that will prevent us from using and
contributing to majority of Phobos even when D2 port is finished.
Switch to input/output ranges as API fundamentals was supposed to
fix it. Custom management policies as you propose won't fix it at
all because garbage will still be there, simply managed in a
different way.
This is especially dissapointing because it was a first time when
declared big effort seemed to help our needs but it got abandoned
after very first attempts.
