What is your use case(s), might I ask? Prevention of array
stomping, I thought, had a net positive effect on
performance, because it no longer has to lock the GC for
thread-local appends.
I would guess they're setting length to zero and appending to
re-use the memory.
Exactly. So far looks like upon transition to D2 almost all
arrays used in our code will need to be replaced with some
variation of Appender!T
From what little I have read about sociomantic's codebase
(pre-allocated lumps of memory, stomped all over to keep code
simple and prevent needing extra allocations, am I right?), I
would imagine you would be better off just emulating the old
behaviour in a little wrapper around a builtin array.
