[Haskell-cafe] compressed pointers?

[Ketil Malde]

One of the downsides of a 64-bit environment is the increased size of
pointers.  This means that the cost of a String increases from
something like 12 bytes per char to something like 24.

I notice BEA uses something called "compressed pointers" to get the
64-bit (more registers, etc) benefits without paying the
(cache-thrashing) cost.

Something for GHC?
