well, i'm not a True GHC Hacker ;) but i was bitten by this problem
in 6.4. i had a lot of SPECIALIZE pragmas in Streams library exactly
because INLINE doesn't help. actually, it even does things worser by
disabling some other form of optimization, i don't remember which one
i have proposal of inlining even recursive functions just for one
level of recursion in order to allow to call here specialized version
of function. what GHC HQ will say?
