Re: BPFK Section: lerfu
Regarding the "close-comma" paragraph, John Cowan commented:
This is historical Loglan terminology, which uses the close-comma (i.e. a comma between two letters) in this function and the open-comma (a comma followed by a space) in the function of Lojban period.
He also clarifes the inclusion of the Other Lerfu:
They were originally inserted as suggestive examples.
