Ummm... as today is still Armistice day  (in my time zone, anyway), maybe we
should call a truce and end this flame war...

Please not. :)
After years of using of R, it is now second nature to me to type (yes,
I always spell out "from" and "to") 
	seq(from=xx, to=yy, length=zz)
and I never understood why the full name of that argument had to be
length.out.  I would hate to see lots of warning messages because I am
using partial matching.
