I did something recently with a page list of "first lines" where I needed
to group them by first letter of the first line. The only way I could get
this to work was with an if following the (:template each:):

(:if ! equal {(substr "{>$FirstLine}" 0 1)} {(substr "{=$FirstLine}" 0 1)}:)
< do something when the first letter changes >
(:ifend:)

substr doesn't seem to work inside a (:template ... :) directive.

Hope this helps.
