Re: [boost] [mpl] multiset

I never need to use helper metafunctions. Meta's expression evaluator handles laziness.

Yes you do use helper metafunctions. Look at your implementation of fold. With a library built with full laziness, you should be able to build a SFINAE- friendly fold like this: template using fold = eval_if, State, fold, lazy_apply>, Fun>

;

Is something like this possible with Meta library? Paul -- View this message in context: http://boost.2283326.n4.nabble.com/mpl-multiset-tp4672187p4673091.html Sent from the Boost - Dev mailing list archive at Nabble.com.
