Lambda C++

After a large time gap between large C++ systems, been catching up on the language. Feels like meeting a high-school friend who you didn’t friend on Facebook.

One of the things that got me to realize that this was not my childhood’s C++ was the existence of lambdas.

At first, I was like: EWWWW… First we had Java envy and now we have Scala envy… does anything ever change.

Except now that I am starting to dig into this little feature, the fact that you can write this piece of code is wicked convenient:

vector<int> v;
v.push_back( 1 );
v.push_back( 2 );
//...
for_each( v.begin(), v.end(), [] (int val)
{
    cout << val;
} );

My personal frustration with using STL may be finally overcome…
