I'm *hoping* it'll speed up execution time, but it's unlikely to make much
impact on hash or array based benchmarks. This is because BCR uses Ruby's
own implementation of hashes and arrays (and all the other standard library
objects, including classes). It might eventually shave a bit of time
off such benchmarks, but that'll only be because method calling has become
slightly faster, and not because of any speed-up in the underlying
implementation of hashes and arrays, which I'm not intending to touch.

There is a little benchmark included in example.rb - run 'ruby example.rb
go' to 
see the results. I'm not going to publish them here because it's not
comparing like with
like: BCR doesn't yet implement the proper Ruby language (eg no argument
count or private /
protected status checks), and so gets an advantage over the standard Ruby
interpreter. On 
the other hand, BCR hasn't been optimised at all yet, and there's plenty of
scope for
optimisations. But please try it yourself and draw your own conclusions!
