<p class="MsoNormal">Hi all,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Let me add the goals I had in mind last time I considered trying to split base.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal"> 1. I'd like to have text Handles use the Text type and binary Handles use the ByteString type. Right now we have this somewhat awkward setup where the I/O APIs are spread out and bundled with pure types. Splitting base would let us fix
this and write a better I/O layer.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal"> 2. The I/O manager currently has a copy of IntMap inside its implementation because base cannot use containers. Splitting base would let us get rid of this code duplication. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm less interested in having super fine-grained dependencies in my libraries. More packages usually means more busy-work managing dependencies. Taken to its extreme you could imagine having base-maybe, base-bool, and whatnot. I don't think
this is an improvement. Splitting base into perhaps 3-5 packages (e.g. GHC.*, IO, pure types) should let us get a bunch of benefits without too many downsides.<o:p></o:p></p>
