Budu stuff... :)
Budu? Wikipedia tells me that's a fish sauce. Hardly complimentary. ;-)
The signature of bimaps insert is the same as standard map inserts. I have a question about the performance of this. Will make_pair create a std::pair?
Yes.
If this is true we are there is an extra copy of each element that I would want to avoid.
Possibly not, if your compiler does RVO.
Is there a way to xpressivize the following code:
result.insert( map_type::value_type(s1,s2) )
Yes. sregex pair = ( (s1= +_w) >> "=>" >> (s2= +_d) ) [ ref(result)->*insert( construct<map_type::value_type>(s1, as<int>(s2))) ]; Pls sync again, if you can. :-P -- Eric Niebler Boost Consulting www.boost-consulting.com
