Subject: [Boost-users] A Special Note for Boost 1.52.0 and Higher - how this affects me?

Hi,

I've just read the Special Note for Boost 1.52.0 and Higher. I must say
that I don't fully understand what's going on and how this affects me.

I'm using some of Boost's libraries with gcc on Ubuntu. Most often it's
gcc 4.4.3, sometimes 4.6.3 but without C++0x mode.

Does the change in boost::result_of affect me in any way? Can it make my
code fail to compile or make it behave in a different way than before?

I just don't understand whether a switch from Boost 1.51.0 to 1.52.0 may
do any harm to my code.

WBR,
Adam Romanek

Yes.

If your code is well-written, it shouldn't.

The note tells you where to go if you want to learn more:

http://www.boost.org/doc/libs/1_52_0/libs/utility/utility.htm#result_of

Only you can answer that. You must read the docs for result_of and
consider your code's usage of result_of.

Your code can potentially stop compiling until you fix the invalid
usages of result_of. The docs tell you under what circumstances this can
happen, and what to do to fix it.
