Sorry to be posting a simple question to the net, but I can't find the
answer anywhere.

The function readsPrec is defined within the Text class.
- What does the "Prec" bit stand for; and
- why does readsPrec require an Int value (I can't see why this is used).
	[the type being readsPrec :: Int -> ReadS a]

I've been looking for answers in the Haskell Report (v1.1) and every place
that readsPrec is used the Int value is thrown away.  Why not use reads
within the class?

Thanks very much for any help.
