Sure, but alloca has the same ugly interface as malloc. :/
You mean that you have to specify how many raw bytes you want, then
cast it to what you need? I never thought alloca or malloc were that
ugly.
The interface of alloca() is bug-prone. And it's not handy if you want
to create a 2D or nD array on the stack :-) In bugzilla there is a
preliminary request for better and less bug-prone VLAs for D.
^ I know you're aware of this, but maybe others might not know the
default-argument alloca wrapping trick:
I've just realized this doesn't work for variable-length allocation:
T[] stack(T)(size_t N, void* m = alloca(T.sizeof * N))
Error: undefined identifier N, did you mean alias T?
N is not visible in the caller's scope.
