It's certainly possibly to define or use State in a way that it gives the impression of modifying a global state, it therefore having a side-effect.

Can you give an example? I don't see how that can be done using Control.Monad.State(.Strict).State, unless invocations of put or modify are considered side effects.
That' the only thing I can figure, but it's easy to show that it's not actually global state (trust me, I had to find ways to make it do global state for GUI callbacks. pain!) -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
