Can you give a reference to Jan Meeus's book?  A simple book search on 
Amazon didn't turn it up.  A Google search for Jan Meeus suggests that 
maybe it should be Jean Meeus (aka Jan Meeus), and Wikipedia lists a 
collection of books by JM on spherical and mathematical astronomy - but 
leaves open the question of which one(s) you used as a basis.  Did you 
compare it with "Calendrical Calculations: The Millennium Edition" (see 
http://www.calendarists.com/)?

The suggested name spaces looked good to me.
