Naming Voldemort Types

["Nordlöw" via Digitalmars-d]

I've noticed that the namings of lazy range voldemort types are 
inconsistent in Phobos. Some are named `XResult` others just 
`Result`, given that `x` is the parenting algorithm. What's the 
policy here?

I would prefer the verbose `XResult` as it's more self 
documenting when debugging or using for instance pragma(msg, 
typeof(r)) where `r` is an instance of a lazy range.

What do you guys think?
