No problem, only AFAICS, the current test is more of a 'do _xlfn.-functions import correctly' kind. 
Should we add all new/renamed Excel2010 functions to that xlsx-document? 
It isn't too much trouble for me, but I wouldn't like to give 'one of you with Excel' work that is not necessary. :) 

BTW, I would put all functions in the xlsx-document at once, and only add the test when adding a set of functions.
