Proposal: Add Text.Read.maybeRead :: Read a => String -> Maybe a

7 Feb 2008

      This function is typically defined once per project. So its
about time this safe variant of 'read' made it into the base.

    maybeRead :: Read a => String -> Maybe a
    maybeRead s = case reads s of
        [(x, "")] -> Just x
        _         -> Nothing

Consideration period: 1 week.

Patch to Text.Read attached.
