Non-constexpr TIMES

[Swassie]

Hey

Currently the TIMES macro requires that its argument must be constexpr. This makes it not possible to use in a parametrized test or helper function where the number of calls depends on some parameter.

What is the reason behind this limitation, and can it be removed?

Thanks

The reason is that the limits are expressed in the type system, and are used for many compile time checks. It may be possible to make it a runtime limit, probably with somewhat worse compile time error discovery, but it would be a substantial change.

[Swassie]

I think it would be a good change, especially since the workarounds (e.g. counter variables) aren't very good. The code would be cleaner and easier to understand if TIMES could be used in both cases.

PR is welcome. I think it may be possible, but I don't know how to just yet.

[Swassie]

Sure, I can give it a try.

I'm giving this a bump, as I would really love to see this to be possible.
