unique_copy is overloaded on forward- and output_iterators for the result
iterator; the output_iterator version requires Assignability on the input's
value_type, which isn't required by the resolution to DR #241:
http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#241
I'll attach a demonstration, which compiles on at least one other
implementation. When using only input AND only output iterators,
implementations must keep a temporary copy somewhere; is the standard implying
that implementations use placement new for that?
