A perennial question on the cpplang Slack:
“When I call v.clear() on a vector, does that hang onto the heap allocation,
or free it?” The short answer is: “It hangs onto the allocation. Follow up with
v.shrink_to_fit() if you need the allocation eagerly returned.”…

Back in 2021, I wrote that “Semantically ordered arguments should be lexically ordered too.”
Two minor updates in that area, which are large enough to deserve a post of their own.

With this post I will concentrate on the here and now: how to use C’s future lifesaving defer feature with existing tools and compilers.
