The RSpec Book says: "Liz Keogh has been exploring similar templates
that reorder the points of focus and solve problems related to
expressing business value. For example, when a narrative suggests
"As a visitor to the site, I want to log in," it’s unlikely that
a real visitor actually wants to log in. It’s the security manager
that wants the visitor to log in, so that’s the role that provides
context for business value, even though the visitor is the active
role in the narrative."
