Re: [Haskell-cafe] Left fold enumerator - a real pearl overlooked?

Can someone point us to some resources about these? I for one have not heard of them before On Sat, Feb 28, 2009 at 12:59 PM, Johan Tibell wrote:

Hi all,

in the last few months I was looking for haskell database library, eventually settling for HDBC (thanks John btw).

Takusen also caught my eye although I even failed installing it.

Nevertheless a particular property of takusen, left-fold-enumerator, also sparked my interest and I tried to follow it up.

I had the impression this is something of relevance but something that is not mentioned or made use of often. There are actually only a few references on the net and most of those by one person only, Oleg.

There was one post from John Goerzen about Haskell HTTP libraries in which he hinted using left-fold enumerators.

Anyway what I'm saying is that the whole topic is somewhat off the radar of the larger haskell community, how come, or am I merely overestimating its relevance and usefulness?

A couple of people (me included) have been discussing different possible designs outside this mailing list. I think we're getting a better understanding of the design space but I feel like there's more to be discovered which is probably the reason none of us have release a library that makes use of left fold enumerators.

Cheers,
