A long, long time ago, in a galaxy far away, a language was forged, so powerful and shrouded in mystery that, although it has permeated and influenced a whole host of other languages, it remained obscure and generally unknown.

Self

Unfortunately, this will stay this way for a little bit longer, since I cannot seem to get it running on my machine, it keeps complaining:

chi ~ % Self -s /usr/share/self/0/Demo-4.4.snap
for I386:  LogVMMessages = true
for I386:  PrintScriptName  = true
for I386:  Inline = true
for I386:  SICDeferUncommonBranches = false (not implemented)
for I386:  SICReplaceOnStack = false (not implemented)
for I386:  SaveOutgoingArgumentsOfPatchedFrames = true

  Welcome to the Self system!  (Version 4.4)

It should be a smooth ride if you're on OSX, since that's what the developers seem to use, but for now I've filed an issue and await further instructions.
