Re: [Haskell-cafe] question about show

Then you write a custom show function that does the best it can. For what it's worth, Smalltalk has historically had thing printOn: stream write thing on stream for people to read thing storeOn: stream write thing on stream so that #readFrom: can read it back and functions (which Smalltalk calls 'blocks') basically defeat both of them.
