Allocating an Array segment of a primitive type with 1 initialized element.

[Philip Race]

MemorySegment.allocateArray()  has these variants

default MemorySegment allocateArray(MemoryLayout elementLayout, long count)
and
default MemorySegment allocateArray(ValueLayout.OfLong elementLayout, 
long... elements)
default MemorySegment allocateArray(ValueLayout.OfInt elementLayout, 
long... elements)
(etc)
and in all cases the first arg is a MemoryLayout

eg it could be this
ValueLayout.OfLong JAVA_LONG;
where
ValueLayout.OfLong extends ValueLayout
ValueLayout extends MemoryLayout

So what happens if you want to allocate an array of length 1  with value 
10 ?

You'll try something like
MemorySegment.allocateArray(JAVA_LONG, 10);
but that doesn't get you what you expected

import java.lang.foreign.*;
import static java.lang.foreign.ValueLayout.*;

public class AllocArray {

   public static void main(String[] args) {
     try (Arena arena = Arena.ofConfined()) {
        MemorySegment lseg1 = arena.allocateArray(JAVA_LONG, 10L);
        MemorySegment lseg2 = arena.allocateArray(JAVA_LONG, 10L, 20L);
        MemorySegment iseg1 = arena.allocateArray(JAVA_INT, 10);
        MemorySegment iseg2 = arena.allocateArray(JAVA_INT, 10, 20);
        System.out.println("long seg1 size = " + lseg1.byteSize());
        System.out.println("long seg2 size = " + lseg2.byteSize());
        System.out.println("int seg1 size = " + iseg1.byteSize());
        System.out.println("int seg2 size = " + iseg2.byteSize());
     } catch (Throwable t) {
       t.printStackTrace();
     }
  }
}

% javac --enable-preview -source 22 AllocArray.java
% java --enable-preview  AllocArray
long seg1 size = 80
long seg2 size = 16
int seg1 size = 40
int seg2 size = 8


I get that allocating an array of length 1 is not common but it still 
seems a bit off, and
I'm surprised the compiler didn't prefer the more specific case.
Unless I am missing something it seems to me that for the sake of 
clarity that
the first version should be renamed allocateArrayOfLength(), or
the second renamed to something like allocateArrayFromValues()
