Let return{expr} Be Explicit, Revision 2

by Herb Sutter

Excerpt:

This paper is a followup to N4029 to follow EWG preference for a variation on that proposal, namely allowing explicit constructors to be called by the syntax return {expr};, with the same semantics as initializing a local variable using return_type var{expr};. This addresses EWG issue #114.

Thanks to Richard Smith for his assistance with the proposed wording. Thanks to Peter Dimov, Gabriel Dos Reis, Howard Hinnant, Stephan T. Lavavej, Mike Miller, Bjarne Stroustrup, Ville Voutilainen, Jona-than Wakely and all others who provided comments on this topic and/or drafts of this paper.
