TPL suffixes are sometimes inconvenient. I implemented a wrapper that derives from BOOST_TYPEOF(wrap(something)) in emulation mode. The wrap function is template<class T> mpl::identity<T> wrap(T&); It's somewhat similar to BOOST_TYPEOF_NESTED_TYPEDEF but not a replacement for it. Is there any interest in my idea? BTW, BOOST_TYPEOF_NESTED_TYPEDEF cannot be used at function/block scope but this fact is not documented. -- Alexander Nasonov http://nasonov.blogspot.com Good manners will open doors that the best education cannot. -- Clarence Thomas -- This quote is generated by: /usr/pkg/bin/curl -L http://tinyurl.com/veusy \ | sed -e 's/^document\.write(.//' -e 's/.);$/ --/' \ -e 's/<[^>]*>//g' -e 's/^More quotes from //' \ | fmt | tee ~/.signature-quote
