yes.

That’s all AutoBailout does, it is just Ovid’s code packaged up as
a tiny module. That is why I suggested shipping it with Test::More.
I cannot imagine it ever causing a burden (though I’m fine with shipping
it separately too). Just because it does so little, bordering on nothing.

Well, does it need to? Test reports will contain STDERR anyway. All you
lose is that the error message is a bit more raw.

I like that.
