Is it possible to return an Objective C BOOL datatype from a camelbones perl subrutine?

The datatype section of the documentation lists a bunch of datatypes, but none of which are BOOL.

To give a little more detail, I am trying to implement the tableView:shouldEditTableColumn:row: method of the NSTableViews class.  The method returns a BOOL type.

Objective-C's BOOL (unlike C++'s bool) is just a typedef - it's really a char. So you can declare BOOLs as 'c'. (I'll make a note of that in the docs.)
