In his book The C++ Standard Library (Second Edition) Nicolai Josuttis states that lambdas can be better optimized by the compiler than plain functions.
In addition, C++ compilers optimize lambdas better than they do
ordinary functions.

Why is that?
I thought when it comes to inlining there shouldn’t be any difference any more. The only reason I could think of is that compilers might have a better local context with lambdas and such can make more assumptions and perform more optimizations.
