It doesn't have to go in, but I think it would be nice. I'd like to<br>
have it out for at least one major release in a disabled-by-default<br>
state so that we can experiment with it. But as far as my particular<br>
goals for this feature are concerned, I'll backport the patch to 7.10<br>
and use it in our local GHC build at Facebook regardless.<br>
<br>
Luite - the hooks you use are still intact, so I don't think you have to<br>
do any major restructuring in GHCJS until you're ready. What I've<br>
implemented will almost certainly need work to be usable or shareable<br>
with GHCJS, and it's not clear to me exactly what the changes will look<br>
like, but for the time being I thought the changes should not impact<br>
GHCJS's implementation of TH & GHCi. I could be wrong though, if so<br>
please let me know how it breaks you.<br>
<br>
Cheers,<br>
