So it looks like we're stuck at pretty much the same proposals for the

a) standardize on MPTC and FDs using rules from CHR paper.
b) don't standardize anything, and wait for ATs to take over
c) punt---standardize the library and exact form of FD for that library,
but no more, or

- We're already in that state. There *is* a lot of Haskell code that
uses FDs, it's just not Haskell 98 code. Whenever ATs take over, we'll
still have to deal with this code.

| Hi,
Hi,
I´m trying to make a searchable transactional cache using STM. The
whole idea is to use indexed TVar variables using a FiniteMap. another
TVar holds the finitemap . This last TVar has to be a global variable.
I found that when handled as global, a TVar does not keep the state.
For example:

Funny this should come up. We've just had several submissions to work on
a functional shell for the google summer of code.
Here's a bit of a summary of what's been done in Haskell I prepared a
while back.

Of course the above could no doubt be improved but surely it is already far
easier to understand and much more powerful than the idiosyncratic text

-- catenate all files in a specified directory
catenate outputFile dir = withDir dir $
ls = cat outputFile
So, you would apply this like
catenate result /etc/stuff ? String literals need quotes?
It would also be wise to look at occam and erlang and see if they have
any useful ideas. And, of course, Windows PowerShell.
And scsh (Scheme shell, pretty full featured these days): http://www.scsh.net/
