Yes.  I want to store all 16 bits.  Do whatever is the sensible thing.

The comment in #at:put: is definitely at odds with what the primitives do.

My personal preference is for unsigned byte, word, and long storage to have better naming (e.g. U8Array, U16Array, U32Array with #at:put: storing unsigned integers to  16rFF*) and have these subclassed for (S8Array, S16Array, S32Array) with #at:put: expecting signed integers of the proper size.

Number implementations are way too complex and should be explained better for beginners.

Thanks for the digging,
