[Haskell] ANNOUNCE: ParseP library 0.1

> Unlike ReadP ParseP can handle any type of token, and actually generates 
> error messages in case something goes wrong. It is also possible to use 
> things other then a list as an input stream, for example ByteStrings.
> 
> In addition to the unbiased choice provided by ReadP, and a 'greedy' 
> choice operator similar to the behavior of Parsec (when using try), 
> there is also what I call a 'soft biased' choice. This operator prefers 
> the left alternative, but not if it leads to parse errors later on. For 
> example
>  > runParser ((lit 'a' <<|> return ()) >> lit 'a') "a"
> will not lead to errors, while it would be an error with other biased 
> choice operators.

> An obvious advantage of ParseP over Parsec is that you don't have to 
> mess with 'try'. Also, all alternatives are parsed in parallel, so no 
> backtracking is needed. But I have no idea how the performance would 
> compare in practice.
> 
> Also, I am not to happy about the name, does anyone has any other 
> suggestions?
