Hi Steve,

seq.map and seq.reduce take an operator as their first argument, and a  
sequence as their second.  seq.filter takes a sequence as its first  
argument and an operator as its second.  Is there a reason for the  
inconsistency?  I see that you can chain filter, but this implies that  
you can't chain map?  Reading further through the docs, you do chain  
map - presumably the method map has a different argument order than  
the function map?

Cheers,
Geoff
