Not that this code should mean anything, but at least it should not print
this low-level backtrace.

Now it fails saying you can't call map with that​:

Cannot call map(Int​: Int, Int, Bool); none of these signatures match​:
  ($​: Whatever, *%_)
  ($​: &block, :$label, *%_)
  in block <unit> at -e​:1

Test added to S32-exceptions/misc.t.
