Heck, it's simple enough. I just checked in the fix on trunk. Let me know how that works for you.
OK the base case is working now. I just got a last small problem.
If I try to evaluate :
m = l+k, x = x + y;
I suspect that this is due to a recent change in as_child/as_expr. They used to return references even when they clamed (via result_of) to return values. This was to elide unnecessary copies. But this doesn't work in a world where decltype and auto exist and can independently compute the actual return type of a function. I had thought RVO would eliminate the copies for me, but I must be doing it wrong. I'll try to put it back like it was before until I can't figure it out. -- Eric Niebler BoostPro Computing http://www.boostpro.com
