Who knows, please, how to work with the program of
main = interact (\ s - shows (read s :: Bool) \n)

Is this a GHC bug?

Generally speaking differences that you see between the interactive

There's nothing inherently imperative about bignums. The current
algorithms may have an imperative flavour, but that may be partly
because that's what suits the implementation language. If the
algorithms are divide-and-conquer, perhaps a tree representation would
work very nicely.
And even in

When intending to write a library for large numbers,
it worths to keep in mind the following.
1. Efficient multiplication, division and gcd methods may occur
rather involved mathematically.
2. It is natural for `arithmetics' to include factorization.
Suppose, GHC would like to
I have installed ghc-5.02.3 and ghc-cvs-6-4-branch-June-15

DoCon-2.06 - ghc-5.02.3
to DoCon-2.09 - ghc-cvs-6-4-branch-June-15
on computer algebra (the CA algorithms are the same).
1. They work correct.

Bignum arithmetics and algebraic numbers are worlds apart.
Sergey - as always - is ambitious to perfection. That's good, but

Hi All,
In Simon Thompson's The Craft of Functional Programming Second Edition,
page 226, it is mentioned that Laufer (1996) describes a Haskell
extension to allow dynamic binding. I was wondering if this has been
implemented as an extension in any of the haskell compilers, or variants?
