But not the nollitons. If you write a library, you write it for the
nollitons! Users are going to call these functions. 
calender:date_to_greorgian_date/1 may be a nollition, it is supposed to
be that.

Thus, the concern are the nollitons and singletons not in the manual
pages, they are the really uglies... You are not going to tell me
that you checked all manual entires for the 8148 functions, did you?
