When was the last time you measured? I thought the speed has largely
improved since Steve integrated his work.
I have timed it after that integration. I have seen a performance
improvement, but it's small. I can perform some syntactic benchmarks.
Performance was vastly improved for situations where one was appending to
multiple arrays at once. For appending to a single array in a loop, it is
improved, but not that much.
But the main improvement was for safety. The append operation on D's
dynamic arrays is a tradeoff between footprint, speed, and safety. It
also does not and should not compromise performance on operations besides
appending.
You will always be able to outperform the D append operation with more
focus on the append operation, but D's array appending is fine for most
situations.
