> Two (byte) buffers are equal if their contents are equal.
> However, currently, {{BufferData}} comparison ({{PartialEq}}) uses its
> {{capacity}} as part of the comparison. Therefore, two slices are considered
> different even when their content is the same but the corresponding
> {{BufferData}} has a different capacity.
> Since this equality is used by {{Buffer}}'s equality, which is used by all
> our arrays, currently arrays are different when their contents are the same
> but the underlying capacity is different. I am not sure that this is what we
> want.
