Title of Next Page in Paginator

I was wondering if there is a way to access information about the previous and next entry when pagination. For example, right now I have:

{{ if .Paginator.HasPrev }}
  <a class = "left" href="{{ .Paginator.Prev.URL }}"> 
    &larr; Previous Page
  </a>
{{ end }}

But what if I wanted to have the title of the previous page instead?

A pager in a paginator does not (currently) have a title:
