I am working thru Implementing Functional Languages: a tutorial and I
want to look up one of the references to get more details.
I am looking for the book The implementation of Functional Programming
languages by S. L. Peyton Jones.
Anyone know how I can get it? I would be willing to pay for

Hi,
it might be better to use a simple abstact data type for it like:
You probably meant algebraic data type. Abstractness isn't essential
here.

You can use exisential types to do what you'd like. From memory, so
there are probably errors:
newtype ServerCommand = forall a. ServerCommandClass a = ServerCommand a
This can't be newtype, you must use 'data'.

Hello
Strings in haskell seem to be one major source of problems. I try
to outline some of the problems I have faced and possible solutions.
Size
Handling large amounts of text as haskell strings is currently not
possible as the representation (list of chars) is very inefficient.

Efficiency is always a reason to mess everything. But the inefficiency
applies to lists of every data

Would it not bet better is String were a typeclass instead of a data type.
Then the string operations could be redefined by implementation, so you
may have strings as lists or strings as arrays?

It would be nice to have a Sequence type class which provides a uniform
interface for common operations on List and Array, Lists of Arrays and so
on. Then String could be based

You know about the PackedString functions, right?

Yes, but they are quite broken. I am using FastPackedString from
darcs for many purposes, which is like PackedString in many
ways.
G'day all.
Quoting Henning Thielemann [EMAIL PROTECTED]:

OTOH, when efficiency matters, it REALLY matters. (The flip side of
this is that efficiency doesn't always mean what you think it means.)
The problem is that the current representation
