[Haskell-cafe] Float instance of 'read'

A small annoyance some users outside
english speaking countries usually
experiment when learning programming
languages is that real numbers use
a '.' instead of ','. Of course, that
is not such a problem except for the
inconsistence between computer and
free hand notation.

Do you think 'read' (actually,
'readsPrec'?) could be made to also
read the international convention
(ie., read "1,5" would also work
besides read "1.5")? I'm happy to
finaly use a language where I can
use words of my language to name
variables, so I wonder if we could
also make that step.
