How about a stack allocator like this:

enum StackSize = 8192;
struct Stack {
static Stack it;
void[StackSize] _buffer = void;
size_t _bufUsage;
void[] take(size_t N) {
if ((this._bufUsage + N) <= StackSize) {
scope(exit) this._bufUsage += N;
return _buffer[this._bufUsage .. this._bufUsage +
N];
}
return null;
}
void reset() {
this._bufUsage = 0;
}
}

Would that fit in std.allocator?
That's std.allocator.InSituRegion, just that is misses the
reset() method.
Nice! But I suggest two things:
1. Add a reset function for reusing the same storage
2. Should that:
https://github.com/andralex/phobos/blob/allocator/std/allocator.d#L2907
not be replaced with ubyte[size] _store = void; ?
