-#####
-#
-# It is impossible to place the awl on a statusbar together with other items,
-# because I do not know how to calculate the size that it is going to get

-# This is what is missing to make a nice script out of awl.

-# {{{ UTF-8 PROBLEM
-#####
-#
-# Please help me find a solution to this:
-# this be your statusbar, it is using up the maximum term size
-# [[1=1]#abc [2=2]#defghi]
-#
-# now consider this example:i
-# "ascii" characters are marked with ., utf-8 characters with *
-# [[1=1]#... [2=2]#...***]
-#
-# you should think that this is how it would be displayed? WRONG!
-# [[1=1]#... [2=2]#...***   ]

-# this is what Irssi does.. I believe my length calculating code to be correct,

-	# Methods for the CALLSTATE class.
-	#  Basically, CALLSTATE objects represent the state of the dispatcher,
-	#   frozen at the moment when the method call was dispatched to the
-	#   appropriate sub.
-	#  In the grand scheme of things, this needn't be a class -- I could
-	#   have just made the callstate data-object be a hash with documented
-	#   keys, or a closure that responded to only certain parameters,
-	#   etc.  But I like it this way.  And I like being able to say simply
-	#   $cs->NEXT
-	#  Yes, these are a bit cryptically written, but it's behoovy for
-	#   them to be very very efficient.
