Numeric literals

> In GHC, you can do this:

>    import Exception

> 	do result <- catch (evaluate (read "foo" :: Int)) (\error -> ... )


Note that this works in Hugs too.
Well, it does in the cvs repository version...

[Personally, I'd write this code the way Patrik and use exceptions
only for those cases which can't be handled any other way or where
the overhead of threading exceptions around is too high.]
