Re: want better error msg with Class Read

Why not just define your own function, much like `read`, that produces a more suitable error message?

readsPrec (i.e., the class method) doesn't report how far it got when it reports failure. One could change that but this requires a change to the report and to the code compilers derive when you type 'deriving Read' and the code in the prelude and any libraries you use. This is worthwhile but is quite a large change. -- Alastair Reid alastair@reid-consulting-uk.ltd.uk Reid Consulting (UK) Limited http://www.reid-consulting-uk.ltd.uk/alastair/
