I've heard that the implementation of optimistic evaluation was rather
complex, which was the main reason not to include it in GHC (yet).
That's w

I need to pass a big 2-dimensional array of doubles from a legacy
C code to a Haskell module. Of this huge array, the Haskell code will
actually use only
a few elements (say, 10 out of 100x20 matrix). Unfortunately, the C code
does not know
which data are actually needed in the Haskell module.

Hi all,
What is the status of Rob Ennals' optimistic evaluation work? I'm told
that it has been removed from GHC. This is extremely depressing to me.
Without such a feature available, it becomes very difficult to write
programs that process large amounts of data in Haskell. In many such
applicati
I agree 100% with you. We absolutely do intend to support 6.4.2 as a
stable compiler for a long time yet. But this particular bug has been
in the compiler for years, and only reported once. I very much doubt
that anyone will even notice whether or not we fix 6.4.2.
Still, if any two people (
