[Haskell-cafe] Native CLient

I guess I'm confused by what it means to "support" this in a language.

My understanding is this is using lightweight virtualization technology
(perhaps via segment register hacks on x86, and something else on ARM) to
provide a safe sandbox to run native code in a browser.  If I had to guess,
I'd say you could run an entire virtualized OS in there, similar to the way
it was done for vx32 with the Plan 9 port to it.  (9vx is a port of the plan
9 operating system to vx32, allowing it to run as a user process on linux,
freebsd, and Mac OS X)

Are you talking about porting the GHC Haskell runtime to NaCL?  If so, then
I think I understand, but the language itself doesn't really need to do
anything special to support this as far as I can tell.
