# Note that as in the SIOC reference documents, the extended SIOC types
# ontology is referred to as sioc_t.

It would seem that 'reference implementations' of existing ontologies are
actually quite difficult in Spira.

sioc:topic references an RDF Resource.  That Resource may optionally be a
sioc_t:Category or sioc_t:Tag.  sioc_t:Category is a subclass of skos.Concept,
but sioc_t:Tag is its own thing.

I hacked up methodmissing's promise to rename it to ExtPromise.  Then I edited the benchmark program like so:

require "benchmark"
require "ext/promise/promise"
require "promise"

TESTS = 1000
Benchmark.bmbm do |results|
  # Picked inspect instead of undefined, as the pure-ruby promise will raise an 
  # exception on undefined instead of return the promise value
