Original Highlight Excerpt
"Move semantics enable the transfer of resources and ownership between objects"
Whisper Note
This is exactly why modern C++ feels so much safer than the old pointer juggling days.

Original Highlight Excerpt
"the destructor releases the resource and never throws exceptions"
Whisper Note
Makes sense, but what if cleanup itself can fail? Then you're stuck.

Original Highlight Excerpt
"the destructor releases the resource and never throws exceptions"
Whisper Note
If it throws in a destructor, you're basically asking for std::terminate.

"binds the life cycle of a resource that must be acquired before use"
Whisper Note
Doesn't that just mean 'don't forget to free stuff' with extra steps?

"binds the life cycle of a resource that must be acquired before use"
Whisper Note
I've been doing this in C++ for years without even knowing the fancy name.

Original Highlight Excerpt
"binds the life cycle of a resource that must be acquired before use"
Whisper Note
Wait, so it's basically the object's destructor doing the cleanup, right?

"A non-empty comma-separated list of template parameters, used to provide names to the template parameters of a generic lambda"
Whisper Note
Wait, I thought generic lambdas used auto — this is new to me.

"A non-empty comma-separated list of template parameters, used to provide names to the template parameters of a generic lambda"
Whisper Note
So this is just for naming the template params, not the actual types?

"Constructs a closure (an unnamed function object capable of capturing variables in scope)."
Whisper Note
I still can't tell if that's better than just writing a normal function.

"Constructs a closure (an unnamed function object capable of capturing variables in scope)."
Whisper Note
does this mean it's basically a functor but with less typing?

"Constructs a closure (an unnamed function object capable of capturing variables in scope)."
Whisper Note
so basically a lambda is just a hidden struct with operator()
