Patch applied in 3bbb1c4, thanks! Based on moritz's suggestion I switched the call to unpolar to be a method call instead of a subroutine call (we can always switch it back).
I also eliminated the extra calls to 'return', and added the 0-argument parens to the method definitions (which we likely need to add to many of the methods in settings, as well as the specifications in S32). Thanks, Pm
