Hello all,
Is there a way to access the outer class `this` from a local class but without using inheritance? snip...
Shouldn't you be asking this in a C++ NG. It has nothing to do with a Boost library.
Well, I didn't mention it at all but I am dealing with this in trying to implement constant-correct block invariants and loop variants for Boost.Contract with mechanisms inspired by Boost.ScopeExit as indicated by Alexander below. Therefore, the solution of this problem _could_ be related to future Boost libraries... To be honest, I am interested about what Boosters have to say about this problem (because I received many enlightening suggestions before). If you can indicate a couple of good C++ NG I will be happy to pose the same question there. Thanks. On Thu, Apr 15, 2010 at 7:02 PM, Alexander Nasonov <alnsn@yandex.ru> wrote:

Sorry for the late reply, I'm not following every boost thread, I got this message via google alerts.
Yes, this has not been done. Local function can borrow argument binding syntax from ScopeExit but there are other things I need to think of. For instance, in
int BOOST_LOCAL_FUNCTION(f, (BOOST_LOCAL_FUNCTION_BIND( (a)(&b) ), int c)) { // ... } BOOST_LOCAL_FUNCTION_END
syntax, is there any way to shorten BOOST_LOCAL_FUNCTION_BIND to "bind"?
The syntax doesn't have to be exactly as above. If someone could take a lead on this it would be great. I don't have time for this, I'm afraid.
