sconover - 7/2010 - monkey-patch 1=>2==1=>2 The right side was having its braces cut off because of special handling of hashes within arglists within the seattlerb code. I tried to fork r2r and add a test, but a lot of other tests broke, and I just dont understand the test in ruby2ruby. So I’m emailing the author…
