I've recently been made aware of [1] and [2]. GC seems to always 
be a question of what you're willing to sacrifice, and if you 
want low pause times AFAIK the only known way to get that is to 
sacrifice overall throughput. This seems to be contradictory to 
D's goals of efficiency and control to me.

The problem with changing D's execution and/or data model is that 
AFAIK to be viable for a better GC the necessary sacrifices will 
ensure that D cannot compete with C in terms of performance 
anymore. I'm not sure how the majority of the D community would 
feel about that, but I don't think I at least could still 
advocate D as a better drop-in replacement for C.

OT: That's what (GIT) commit hooks are for. Write how you want, 
automatically commit as whatever non-Allman, wrong style the 
project uses.
