While, as you say, addressing this just now might be premature (you've
probably got some more common/basic scenarios to address first) I'll
throw in my 2c of experience with writing lambda-heavy code. Quite
often the lambdas are written as the body of a construct, such as:

std::for_each(v.begin(), v.end(), [](int x) {
  func(x);
});

Some examples in one of Herb Sutter's presentations on lambdas:
