In the past, I've tried both TH and haskell-src-exts to do relatively simple things, but ended-up abandoning them due to the inherent complexity of source level haskell that had very little to do with what I really cared about. Being able to get your hands on Core at the regular Haskell level would truly simplify life, and I suspect would open the flood-gates for a lot of people to develop extremely cool/useful artifacts, making the GHC/Haskell experience even better.</div><div><br></div><div>I hope this idea is taken further and sees the light-of-day.</div><div><br></div><div>Richard: Did you have any further thoughts about possible plans?</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>-Levent.</div></font></span></div>
