Is "with" better than allocaBytes? On Oct 22, 2005, at 12:42 AM, John Meacham wrote:
because haskell values don't have the same representation as C values. haskell values are pointers to updatable thunks. in any case 'with' just allocates 4 bytes on the stack (the same as a auto C declaration) so is quite speedy compared to what it would take to make a haskell value look like a C one. not to mention haskell values can't be modified.
