[Haskell-cafe] Re: Float instance of 'read'

[Mauricio]

Maybe. Doubles 'show' function always print something
after the decimal separator, so 'show [doubles]' is
easy to parse but difficult for human reading. It
would be nice to have a space between elements of a
shown list, though. It's an annoyance, but
internationalization is really great, I think it
deserves the effort.

Best,
Maurício
