Review Comment:
NOTE: I followed the same API that returns `error` for `Append` and
`UnsafeAppend()`. However the only thing that returns error from `appendValue`
and `unsafeAppendValue` is `b.memoTable.GetOrInsert(val)` since `val` is
`interface{}`.
Since here `v` is typed explicitly with `T`, is it safe to assume there
should never be any error. In that case I can change the API to ignore the
error here (I can add a comment). We should also change the API of `Append()`,
but that would be a breaking change.
