      <nixeagle> badipod: this ... is why you profile before you
                 optimize the wrong blasted thing XD  [06:36]
      <nixeagle>     11.417 | 1,049,028,592 |   126 |   0.090610 |

                 INTERN-TREE-SPECIALIZER
       <badipod> lol? .-.  [06:39]
      <nixeagle> badipod: I optimized INTERN-TREE-SPECIALIZER :P
       <badipod> hmm, I seem to remember having problens getting
                 glib...
       <badipod> nixeagle hah XD
      <nixeagle> see... where the real problem is XD
       <badipod> mhm :P  [06:40]
      <nixeagle> 1,049,028,592 << thats in bytes ... so roughly 1GB
                 of memory XD
       <badipod> .-.  [06:41]
      <nixeagle> not used all at one time mind you!
       <badipod> lol
      <nixeagle> we do have smart GC, but the fact that we had to
                 malloc that much ;)
       <badipod> XD
      <nixeagle> anyway all ensure-tree-symbols does is make sure
                 the list is a list of (:keyword :symbols :like
                 :this) instead of (keyword symbols like this) or
                 "keyword symbols like this"  [06:42]
       <badipod> fun :o  [06:43]
      <nixeagle> and badipod here is the cincher! After the first
                 time we call ensure-tree-symbols... all future
                 ensure-tree-symbols is being passed a list that
                 looks like this:  (:keyword :symbols :like :this)
       <badipod> XD
       <badipod> I see
      <nixeagle> highly amusing :D  [06:44]
      <nixeagle> duck will laugh tomorrow :D
       <badipod> ;D
