Subject: [Boost-commit] svn:boost r77917 - in trunk: boost boost/local_function/aux_/macro boost/local_function/aux_/macro/code_ boost/local_function/aux_/preprocessor/traits libs/local_function/test
From: lorcaminiti_at_[hidden]
Date: 2012-04-11 13:14:01
Author: lcaminiti
Date: 2012-04-11 13:14:00 EDT (Wed, 11 Apr 2012)
New Revision: 77917
URL: http://svn.boost.org/trac/boost/changeset/77917
Log:
Implemented a trick for NAME not to use BOOST_TYPEOF without requiring to repeat the function type (doing a typedef on the local class so to access the functor type in NAME).
