There seems to be a bug in facets PQueue v1.8.54, at least the behavior is
inconsistent. Here is the output on machine-1 which is running -

---------------------------------------------------------
ruby 1.8.5 (2006-08-25) [i386-mswin32]
facets (1.8.51, 1.8.8)

irb(main):001:0> require 'facets/more/pqueue'
=> true
irb(main):002:0> pqueue = PQueue.new(lambda{|x,y| x<y})
=> #<PQueue:0x2c35c60 @gt=#<Proc:0x02c35d28@(irb):2>, @size=0, @qarray=[n
irb(main):003:0>
irb(main):004:0* pqueue.top
=> nil
---------------------------------------------
This is the expected behavior

While on another machine with -

-----------------------------------------
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]
facets (1.8.54)

irb(main):001:0> require 'facets/more/pqueue'
=> true
irb(main):002:0> @pqueue = PQueue.new(lambda{|x,y| x<y})
c:/ruby/lib/ruby/gems/1.8/gems/facets-1.8.54/lib/facets/more/pqueue.rb:236:
warn
ing: default `to_a' will be obsolete
=> <PQueue: size=1, top=#<Proc:0x02d9bc58@(irb):2>>
irb(main):003:0> @pqueue.top
=> #<Proc:0x02d9bc58@(irb):2>
---------------------------------------------

Strangely the lambda supplied as the comparator is inserted in the queue.
Both Ruby and Facets version is different.

TIA
