@ironcamel,
Are you aware that Ruby 1.9 is almost a total reimplementation of Ruby? You appear to think it was a minor update.
Internally, Ruby 1.9 has very little in common with Ruby 1.8. In terms of features; Ruby 1.9 adds some major new features and cleans up a few inconsistencies and bugs - one of those bugs being the block variable scoping pointed out in this gist. Nonetheless Ruby 1.9 aims to be more or less 95% backwards compatible with Ruby 1.8 - which it has achieved.
Major releases are allowed to have breaking changes. Ruby 1.9 is a major release, it has breaking changes. In terms of 'expectation' - there were expected to be breaking changes. Once again: It is a Major Release.
Get over it. Everyone else has.
