Missing output during shrinking

[sjakobi]

At sjakobi/bsb-http-chunked@d0d5794 I have a testsuite with a failing property that will shrink forever if you don't pass in --hedgehog-shrinks 5 or something like that.

The problem is that for quite a while I didn't even realize that the property was failing: I had to use hedgehog's checkSequential to find that out.

It would be nice if there could be some output that indicates the failure before the shrinking begins, so I can abort the program if the shrinking takes too long.
