Yes very interested. I have been meaning to get around to remaking
the patch against 4.8 (and previously 4.7) for ages now. Though
getting the time to do so has been, and will likely continue to be, a
problem what with work, fatherhood and other commitments.
Since the gcc/cp code base is significantly different now from the old
lambda branch where the changes were originally made in 2009, my
intent was to remake the changes from scratch implementing the
entirety of N3559 (now N3649) and, at least, the explicit template
parameter specifier syntax from N3560 (though I'm very interested
getting the single expression body syntax working also).
I have no problem with someone else getting on with this as I can't
guarantee consistent availability for it but I will try to get some
time to at least look at my previous aborted efforts to get the
changes applied to the more recent mainlines (I have some git repos
around here and at work with some incomplete changes). I will see how
far I got with these and maybe post a few patches. It is highly
likely though that these were just abortive attempts to merge the
previous stuff or incomplete restarts.
