  16 [heading Description]
  17
  18 `replace_copy` copy every element `x` in `rng` such that the corresponding element in the output range `y` is `x == what ? with_what : x`.
  19
  20 [heading Definition]
  21
  22 Defined in the header file `boost/range/algorithm/replace_copy.hpp`
  23
  24 [heading Requirements]
  25
  26 * `ForwardRange` is a model of the __forward_range__ Concept.
  27 * `ForwardRange` is mutable.
  28 * `Value` is convertible to `ForwardRange`'s value type.
  29 * `Value` is a model of the `AssignableConcept`.
  30 * `OutputIterator` is a model of the `OutputIteratorConcept`.
  31
  32 [heading Complexity]
  33
  34 Linear. `replace_copy` performs exactly `distance(rng)`.
