8181For example, the elements of a `set` are treated as being
8282unordered, but the values will necessarily possess an order by where they are in
8383the memory. Thus if every `set` is stored using the same order scheme then faster algorithms involving `set`s may be
84−written. This is not the same thing as casting - it is forcing a
84+written. Furthermore, if you just place elements in the `set` randomly, it may

86+This is not the same thing as casting - it is forcing a

8688rune should rarely be used, but it is extremely important when it is.
