Thanks for the detailed explanation.


As for the g++ issue, then a minimal testcase that does not include the whole
of <tuple> might be useful to see what could be speed up: See
https://gcc.gnu.org/bugs/minimize.html The testcase itself might generate code
programmatically using macros, for example, but less code without any headers
is easier to analyze.

I cannot say if the libstdc++ implementation could be better, but the way to
prove it is simply to submit a new implementation and convince the maintainers
that it is better with numbers. I'm sure they will be delighted to receive such
contribution. But a draft is not enough. The new implementation needs to pass
all testcases in the testsuite.
