40	Don't demand the whole list with fromList	repa	3.2.2		defect		new	2013-12-14T03:56:32Z	2015-05-19T12:54:12Z	"
If the client tries something like:

{{{fromListUnboxed (Z:.s:.s) [0.0,0.0..]}}}

then the code will stall when trying to determine the length of the list.

13	Optimise Repa.fromByteString to avoid bounds checks in ByteString	repa	3.2.2		enhancement		new	2010-04-30T04:37:56Z	2015-05-19T12:54:19Z	Should be able to use an intermediate CString for this.	Ben Lippmeier
38	Make unsafeWriteMVec for boxed arrays strict	repa	3.2.2		enhancement		new	2013-04-23T02:25:08Z	2015-05-19T12:54:38Z	"
See the following SO question:
http://stackoverflow.com/questions/16097418/parallel-repa-code-doesnt-create-sparks/

We can force an (Array V) to be evaluated by mapping a deepseq function across every element, but this is non-intuitive. It would be better to just make the write function strict and ensure all elements in such an array are properly evaluated. "	Ben Lippmeier
41	Generalise foldS worker to have a different accumulator type	repa	3.2.2		enhancement		new	2014-02-11T11:20:53Z	2015-05-19T12:54:25Z	"With 

{{{
foldS :: (Elt a, V.Unbox a)
      => M.IOVector a   -- ^ vector to write elements into
      -> (Int# -> a)    -- ^ function to get an element from the given index
      -> (a -> a -> a)  -- ^ binary associative combination function

the worker could really have type (a -> b -> b) in the sequential case."	Ben Lippmeier
43	Avoid intermediate lists when packing Ints and Strings	repa-convert	4.2.0		enhancement		new	2015-05-19T12:50:16Z	2015-05-19T13:02:44Z	The packer for Ints uses plain Haskell show, and the intermediate list of Chars won't be fused away.	Ben Lippmeier
