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

There are a number of new things. Sequence wrappers have been added as
recently discussed:
http://lua-users.org/wiki/SequenceAdapters
Can now write things like this one liner:
seq(s):last():filter('<'):copy()
