Understanding Uint8Array Memory Blocks Usage: 3 Bytes Data Consuming 3 Blocks (14 bytes per block)

>var a=Uint8Array([1,2,3]).buffer
=new Uint8Array([1, 2, 3]).buffer
>E.getSizeOf(a)
=2

maybe that is what E.toString takes from the array too in the previous example. Still it is interesting that only the string takes 1 and the arraybuffer needs 2 (and typed array even 3)
