One possibility is using WTiling.managed_i to go through
the list of objects managed by the tiling. RTFM on details,
but, e.g., the following snippet in Mod1+F3 prints the names
of everything (except the somewhat transient stdisp) managed
by the tiling:

_:manager():managed_i(function(x)
                          print(x:name())
                          return true
                      end)

_ is the frame in which Mod1+F3 is opened, _:manager() is
typically the tiling object on tiled workspaces, etc. The
function must return true to continue iteration, false 
(or nil) to stop iteration. Just replace the print with
something that sets a (local) variable outside the iterated 
function to frame count, and stop iteration if this has 
become at least two.
