Not sure why find would return a range - but so long as I can also use it with standard algorithms, and it generates efficient code I'm happy.

I recall the discussion about what range-algorithms should return. My current answer is: std::string src("abcdefghijk"); namespace ph = boost::phoenix; // version2 { std::string s1("efg"); BOOST_CHECK(( equals( std::string("efghijk"), src|applied(ph::search(rng1, s1), end) ) )); } Users specify it by using lambda expression. -- Shunsuke Sogame
