I thought we had gone away from the concept of "pole" error to be more a 
generic singularity. Jerome is the expert.

Also, how about:

 	"Invalid" being raised is generally a domain error

I have a sneaky suspicion there are one or two cases where it is not 
strictly a domain but I cannot recall off the top of my head. I will 
double check.
