[Douglas Gregor]

Author: dgregor
Date: Tue Jan 25 10:14:21 2011
New Revision: 124190

URL: http://llvm.org/viewvc/llvm-project?rev=124190&view=rev
Log:
An rvalue reference cannot bind to an lvalue, so static_cast the
result of the __tuple_leaf::get() call to an rvalue reference when
returning from tuple's get().
