Neil, I hope I can count on your continued support. Your comments are hoping me refine my thinking. What I am attempting to do is ambitious and so I have my work cut out for me. Do I really need quasi-quotes? In a sense I will and in another I won't. That is the best way to describe it. Ther

Dear Neil, Neil: For GHC in particular, they currently have a build system that works, what's the benefit of changing the build system? John: To make it even better. As I pointed out in my GHC ticket system feature request ticket (http://hackage.haskell.org/trac/ghc/ticket/3912) the build sys

I'm in the process of preparing a rather long letter. In short my response is "Fair enough. I'll take that as a challenge." This letter is a meta-discussion. I'm talking about what I'm talking about. I thought to flush out some of my thoughts and respond to objections which I more than happy to

Hi, As Simon says, I've got some experience using Haskell for writing build scripts. I had a fork of the Yhc build script written in Haskell, for example. I think it's a very good idea in general. For GHC in particular, they currently have a build system that works, what's the benefit of changing

As it concerns sources of inspiration is how proof assistants with dependent types implement their module system. Traditionally, a computer programming language consists of more than one sublanguage. A language of expressions and a module language for example. With dependent types it becomes pos

The follow may seem a little like science fiction, but taken to its limit I do not find it difficult to envision a single massive data stream greater than a terabyte that consists of the entire software repository of say a corporation or government and feeding it to the compiler that would globa

When the stream length (file size) is only a few kilobytes applying optimizations to speed the compilation process along isn't especially meaningful. With massive stream lengths there is economy of scale that will likely also translate to producing better machine code and other aspects of the p

The timing for this is good in that new technologies are coming forward that may render the disk operating system paradigm altogether obsolete and not merely grossly inefficient. Moving to a new paradigm now may help position us ahead of the curve.___

I have already anticipated the objection concerning having a means to boot strap the system. One solution is one I already hinted at. The sqlite project solved that problem. I provided a hyperlink to the project earlier. We could follow their lead. It is also possible to do something similar to
