I was browsing through druntime's lifetime.d for an unrelated reason and

Is
there something I'm missing, or is this a bug that somehow noone has
noticed
up to this point?
Array appending does not respect any of the new copy construction
semantics. It basically does a memcpy and that's it. It doesn't even
respect shared (shared data is memcpy'd just like any other data),
although it does use a lock to protect shared appends.
I see there is a postblit function in the typeinfo, so it should be
possible to do the right thing.
One thing I'm unsure of is how postblit works on const or immutable
structs, anyone know? There is no typechecking in the array functions,
everything is a void[].
File a bug on it please.
