We are currently working on resolving issues raised during the committee meeting and hopefully will write a new paper on lambdas. Any feedback on this topic will be highly appreciated.
I was looking at the lambda papers recently and I came to the conclusion that what we actually need is local functions. To pick an example from N1958: void foo( myvec& v, const myset& s, int a ) { // ... v.erase( std::remove_if(v.begin(), v.end(), bool(int x) { return std::abs(x) < a && s.find(x) != s.end(); }), v.end() ); } What I really want is this: void foo( myvec& v, const myset& s, int a ) { // ... inline bool f( int x ) { return std::abs( x ) < a && s.find( x ) != s.end(); } v.erase( std::remove_if( v.begin(), v.end(), f ), v.end() ); } for obvious readability reasons. This syntax also allows me to use a more descriptive name instead of f, and the consistency with ordinary function definitions will make it easier to teach. It may be somewhat easier to parse or specify, but I haven't considered this in detail.
