Late to the party, but congratulations and great work on another 
impressive release! Thanks to everyone involved!


Just wanted to report a very large decrease in build performance.
Compare a debug build on Ubuntu 16.04 64-bit with ld.gold.

with 2.070.2:
real	0m9.775s
user	0m9.036s
sys	0m0.700s

with 2.071.0:
real	0m45.011s
user	0m41.760s
sys	0m3.144s


Since this release is not critical for us, despite including many 
great changes, we will also stick to DMD 2.070.2 and hope for a 
fix in a future release, if at all possible.
