Description

std::tuple is reportedly slow to compile with many types.

Could transition from recursive template:

class tuple<_This, _Rest...> : private tuple<_Rest...> { // recursive tuple definition
...
};

to a non-recursive structure improve it?

Research direction

Start with the recursive std::tuple definition shown in the issue and measure compilation with tuples containing many types. Compare that baseline with a non-recursive structure, if a viable design can be identified. Done means demonstrating whether the change improves throughput without violating tuple behavior.
