Hey, sorry for the bump, but could someone look at the unanswered questions at https://github.com/arrow-kt/arrow/issues/3388?

I'll look at this later today. I was the last person to touch this code so probably I can fix it quickly.

to clarify—there's a good chance nothing is broken at all, and it's a misinterpretation on my side. I asked a few questions to be sure whether this is the case 🙂

So the message itself is definitely expected. It's the default message of a RaiseCancellationException.
Now that I look at it, yes the message is actually completely expected. I thought a suppressed exception was the issue, but no you're just calling stackTraceToString. A decision was made to include the RaiseCancellationException message, but perhaps that should be removed. The note on stackTraceToString reads:

Note, the first line in the stacktrace will be the RaiseCancellationException. The users call to raise can found in the_second line of the stacktrace.

^ I interpreted this as being about the at: lines, I wasn't sure whether it also applied to the message.

I think however Simon pointed out that a different unexpected behaviour was happening, which I'll take a look at later today then, but yes what's happening to you is entirely expected, although should likely be improved. I think the difficulty is that there's no multiplatform way to inspect the stacktrace

That's a fair interpretation. Looking at the impl, it's absolutely just printing the exception with its message and everything.

Therefore I can just hide that message from the user, thanks 🙂

Then it's official: Prepared is the first test framework with Raise tracing support 😇
