10844	flyweight: multiple default constructors with real perfect forwarding	tore.halvorsen@…	Joaquín M López Muñoz	"Flyweight gets two default constructors, since it has a direct default constructor

{{{

flyweight():h(core::insert()){}
}}}


and one based on variable template arguments, which can be zero.

{{{

#define BOOST_FLYWEIGHT_PERFECT_FWD_CTR_BODY(args) \
  :h(core::insert(BOOST_FLYWEIGHT_FORWARD(args))){}

  BOOST_FLYWEIGHT_PERFECT_FWD_WITH_ARGS(
    explicit flyweight,
    BOOST_FLYWEIGHT_PERFECT_FWD_CTR_BODY)

#undef BOOST_FLYWEIGHT_PERFECT_FWD_CTR_BODY
}}}

which can expand to:

{{{
template<typename... Args>
explicit flyweight(Args&&... args) 
:h(core::insert(std::forward<Args>(args)...)){}
}}}
