Thanks for pushing forward with Hoopl and other back-end things.<br>

Did this patch elicit any performance gains? Or what brought it to your attention?<br></blockquote><div><br></div><div>I noticed this some time ago and just now got around to try it out.

Do you have further plans for Hoopl and GHC's back end?<br></blockquote><div><br></div><div>The biggest thing is probably: <a href="https://github.com/ghc-proposals/ghc-proposals/pull/74">https://github.com/ghc-proposals/ghc-proposals/pull/74</a></div><div>Other than that, I haven't made any plans yet ;) There are a few tickets that I'd like to make some progress on.
