Argh. Have any MS Connect bugs been filed to track those variadic template problems? I wasn't aware that

Boost had to turn them off - that's a big deal.

I have finally found the issue. signals2::slot has 2 constructors: slot<F>(const F &f) { init_slot_function(f); } slot(const BindArgs &...args) { init_slot_function(boost::bind(args...)); } MSVC12 always chooses the variadic constructor, so calling it with boost::bind(...) always tries to call boost::bind(boost::bind(...)). If I understand the example in 14.8.2.4.8 of the January 2012 working draft correctly, it should be the other way around, shouldn't it?
