This is really great news!

Small remark: To get dub working you need to copy it from bin
folder to bin64 folder manually. Just adding folders `bin64`
and `bin` to PATH does not work because Dub will you `dmd`
from current folder.
I guess by "working" you mean that dub uses the 64-bit version
of dmd. We could add a 64-bit version of dub to the bin64
folder, too, but I'm not sure the bin64 version of the compiler
has to be the default. It uses almost twice as much memory and
hence is a bit slower:
dmd.exe -m64 -c -unittest std\regex\internal\tests.d
32-bit dmd: 853 MB, 3.280 sec
64-bit dmd: 1445 MB, 3.740 sec
I just tested the performance improvement and it feels twice
as fast as before!
dmd 2.090.0: 879 MB, 10.230 sec (released without optimizations)
dmd 2.090.1: 873 MB, 5.300 sec
Yes, adding a64 bit version of dub to bin64 would solve the issue.
I also agree with you, there is no need to make the 64 version
the default.
It should just be possible, by extracting the DMD zip archive and
setting
environment variable PATH to bin64 to have a working dmd & dub
integration.
Another solution would also be to have 2 dmd windows zip archives
like you have it
for FreeBSD:
dmd.2.090.0.freebsd-32.zip
dmd.2.090.0.freebsd-64.zip
But this requires more effort I assume, maybe this is a solution
for the long
ran and the low hanging fruit for the moment is to add a 64 dub
executable
to the dmd zip archive.
Kind regards
André
