OK, no dynamically allocated timevars then.
But what about the list-of-lists use-case? I think it's pretty natural that,
when a computation consists of several phases, each (or at least some) of
the phases consists of several sub-phases.

Since the order matters for printing, it's a 'list', not a 'set'.

I like abstractions too. But I also see that many people have problems
grokking abstractions when they don't see the implementation or when the
abstractions are not well explained.

Yes. I meant the link-time optimization. See '-fuse-linker-plugin' in
https://gcc.gnu.org/onlinedocs/gcc-8.2.0/gcc/Optimize-Options.html
