Re: [Boost-users] [smart_ptr] make_shared imposes const ref.

Why is make_shared declared as

template shared_ptr<T> make_shared( Arg1 const & arg1 );

rather than

template shared_ptr<T> make_shared( Arg1 arg1 );

since the effect is that if you have a constructor that takes non-const references you cannot use make_shared( ) on it.

I guess it's because your compiler doesn't support && (i.e. perfect forwarding is impossible). http://www.boost.org/doc/libs/1_48_0/libs/smart_ptr/make_shared.html#functio... <> _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

Ah yes, thanks, I'd failed to notice the informative comment answering my exact question! - Rob.
