+1 on fixing this or improving error message.
In my production code I encountered this bug while trying to test the term's
type object
and I added the space after the method to align stuff:
is make-temp-path.WHAT === IO::Path, *.not, 'made path is not === IO::Path';
is make-temp-dir .WHAT === IO::Path, *.not, 'made dir is not === IO::Path';
The second line crashed.
The current error doesn't even include a location, so it has the potential for
a tedious bug hunt.
