are there more zero-initializations that can be optimized in
std.experimental.allocator?
I looked and identified low-hanging fruit in
std.mutation.initializeAll & moveEmplace and in
std.typecons.RefCounted (PR #6698), and in
std.conv.emplaceInitializer (PR #6461).
What did you search for to find these?
Other opportunities would rely on being able to identify if
it's ever more efficient to write `memset(&x, 0,
typeof(x).sizeof)` instead of `x = typeof(x).init` which seems
like the kind of optimization that belongs in the compiler
instead.
So in which cases is `memset` faster than assignment?
Thanks!
