Issue #35

Super rough point for further discussion in NA SG20 small group

[vulder]

@rwdougla Hi, what's the current status of this draft. Should we take a look at it in the next SG20 meeting or does it need a bit more time cooking?

@vulder we took a look at today's meeting, and we will add a few more items.

@rwdougla we made a pass today on the document. We struggled to understand the following code

multiple statements in a single expression

assert([](){
	std::vector v{1, 2, 3, 4, 5};
	for (auto x: v) std::cout << v << std::endl;
}());

Could you please elaborate here why we use the assert here?

If I interpret this correctly, what @rwdougla wanted to note here (should be covered) is that in a context where only one expression is allowed, one can use an immediately lambda to write multiple statements.

@vulder Ok, I will add it back to my pull request
