Oops, I forgot to type the footnote :-)
[1] "concise and complete" might sound like an oxymoron, but it's

Agreed.  That you were experiencing the problem when explicitly

general principles (see my previous post) :-)  NFS is very likely
a red herring.

The animal that coils in a circle is the serpent; that's why so
many cults and myths of the serpent exist, because it's hard to
represent the return of the sun by the coiling of a hippopotamus.
