Topics

• What is the execute-around pointer idiom.
• How/when/why should you use it.
• How does it work under the hood (I'm genuinely curious about this one): -- Why a single use of operator ->() also calls it on the proxy object (effectively calling the operator twice) -- Which mechanism of the compiller allows that -- What else could be done with it
