There's actually an undocumented QuickCheck clone (done for the teaching

I am extremely interested in these bugs. How do I find more info

That's not expected. It's possible that the broken version took

I wonder can anyone else elicit these problems trying to run it, too?
Your test seems to fail for me (on Debian Stable GNU/Linux, 32-bit x86)
after around 26K to 27K requests (with "-c 10"), using a pre-release

I'm hoping for something similar to [:alpha:], etc. that are based
around, say, the first letter of the unicode character classification.
I *can* do what I want by disassembling strings by hand and using tests
based on char-general-c
I think you're looking for #px"\\p{L}".
See the "\p" production and the non-terminal in
