47−Certain runes are used to create expressions that may include arbitrarily many subexpressions. Such expressions are terminated with the `==` rune. For example, the `:*` and `:~` runes are used to create a cell of any length. (The latter is just like the former except that it adds a null value at the end of the cell.) For another example, the `%=` rune used used to make arbitrarily many changes to a given wing value.
