Sorry to reply to my own posting, but... AHA! I see now what's going
on. The purpose of the rank-2 qualifier is to prevent STRefs from
leaking outside of the runST call, and what the code does at the
lowest level is that it passes around a token "state" object to force
the compiler to cor

There is no way that there's 505 source files in SourceGraph... and I

Hey everyone,
I am thinking about creating a particular data structure with an
immutable and mutable version. The key of my problem is that I would
like the user to be able to work with a mutable version of the data
within a non-IO monad and then get an immutable value at the end,

Hi Edgar
No-one seems to have pointed you to the Maestro:

The quantum mechanics one might be the most directly useful, but they
are all great reads:

My favorite approach is something like as described in these:

Hi,
there are numerous examples on how to implement a DSL, but I haven't been
able to figure out how to "design" one.
I mean I have a pretty good idea of the problem domain, I've coded it over
and over again until I got it right. Now I'd like to express that part as

I'm not saying Haskell is unstable. I'm saying that the attitude
expressed in the following quote is at odds with the needs of business:

It's not just about the _number_ of libraries, but the _usefulness_ of
them for solving real-world problems. Haskell has a large number of
libraries that

Yes, this is yet another SourceGraph announcement, this time for version
0.5.2.0 [1].

The changes in this release are as follows:
* Shift overall analysis to the top and per-module analysis to the
end, as suggested by Duncan Coutts.
*
correction, happstutorial is now tutorial.happstack.com.

Hey, first of all, in terms of a platform for promoting haskell
commercially, happstutorial.com actually implements a job board.
Yeah, it's primitive and not feature complete, but on hackage, open
source, and ready for anyone who would like to work on it. (Currently
