This is about my tries to understand monads and handling state - as
you perfectly know - is one of them. I have understood a little about

There are many tutorials available from the wiki at

q = (\x - p)
For example with the State monad, (q) must be some expression which
evaluates to something of the form S fq where fq is a function with
type s - (a,s), and similarly, (\x - p) must have type a -S ( s -
(a,s)). If we choose names for these values which describe
Very Thankyou
I am starting to feel it. I think about it as a 'context' that wraps
some computations, which are handled by compiler environment (please
make me correct if I am wrong). Now I think I need to find out how
this 'monads' fit in solving problems. And for that I must go through
bigger
Ooops - more bugs in my explanation...

I used the source given in ghc-6.4.2\libraries\monads\Monad\State.hs but the
version of state monad that comes with the hierarchical libs is in

Monad Imparative Usage Example
Thanks for your replies. I have not haskell on this computer and I
will try this solutions tonight.
I must notice that IO computations is not the point here. My target is
to have this code for mutable variable 'var'.

monad is not an stateful variable, it's the way to organize
computations, rule to join them (as the Ring of Supreme Power ;) ).

Of course, if you're learning Haskell, you should probably try to
/avoid/ mutable variables for a while.
Along the same line, I note that proposed solutions seem to use
features relatively recently added to the language, is that true?
