[Haskell-cafe] Re: Why?

[David Leimbach]

I understand that this is very much a work-in-progress.  But we have to also
come to the realization that there's people forming "industrial groups" and
such around Haskell, and trying very earnestly to show that it's worth
looking into for serious practical applications.

I do believe that it's important to point out where there is work that needs
to be done to meet all the goals that Haskell wants to achieve such that the
selling points aren't possibly construed by the audience as disingenuous
claims.

Now having said that, this is *not* meant to be a slap in the face of those
who want Haskell to be used in a practical way *now*.  I am in fact one of
them, having created code that has shipped and will continue to ship (at
least until I'm forced to rewrite it... let's hope not) in Haskell in
management systems that may, if our plans work out,  be deployed potentially
all over the world.
