Instead of yielding loc which is taking it out of the box and putting it back
in, access foundParam inside the for loop.

Thanks, David. Unfortunately I'm having a hard time figuring out how
to get the foundParam.
Using your code, I have:
val loc = for {req <- S.request; loc <- req.location} yield loc
val l = loc openOr "Couldn't open"
println(loc)
println(l)
The first println give me:
Full(Loc(View List(nodes), <function>, LinkText(<function>), List()))
While the second shows that I am opening the Box:
Loc(View List(nodes), <function>, LinkText(<function>), List())
If I try to access my Loc object, I get compilation errors. For
example, "val p = l.foundParam" leads to the error "value foundParam
is not a member of java.lang.Object." The toString method works, while
the title parameter gives me the same error. I believe I am using the
latest Lift code (I ran "mvn -U jetty:run") and feel I must be missing
something very simple here.
Any advice is much appreciated!
