Hit on this bug again. Even while knowing you can't put spaces before .WHAT, it took me a couple of minutes trying to find where this error was coming from.

Right now it doesn't even mention the line number. +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.

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.
