As an aside to Jeroen Pluimers' blog entry on Messagepack/BSON, I note that on the Messagepack site, languages represented include Erlang, D, Scala, Haskell, Smalltalk, and OCaml, none of which appear on the TIOBE index top 20, and no entry for Pascal or Delphi.

My point being that the absence of popular support for Delphi and Pascal has much less to do with actual usage than with other factors.
