tryTest{} catches and returns and must be ended with a cleanup{}
block to throw. That is why it's marked with @CheckReturnValue.
The IDE marks the entire block as a huge warning.
Ideally this should really be an error, but that flag only exists
in Kotlin 2.2 and above, which is not out of beta yet, so
add a TODO in the bp file
