I am not making any suggestions, no. Given

I was just curious whether you considered using a stack, whether you had
any thoughts on whether we might ever want to know more than just the
innermost test name.

As I wrote in my original message, my intent was more to raise awareness that
this /could/ be a solution to the problem -- not to recommend/require/demand
any changes.

Nope, nothing pops to mind that this patch as-is shouldn't immediately serve.

I apologize if I was unclear.
