So UU parsers can construct input? The presence of an
empty list in the 2nd slot of the tuple is the only
indicator of errors?
For parsing datatypes without a sensible default value,
what happens?

How about:
import Text.ParserCombinators.UU.Parsing
import Text.ParserCombinators.UU.Examples
pDate :: Pars (Int,Int,Int)
pDate = (,,) <$> pNatural <* pDot <*> pNatural <* pDot <*> pNatural
where pDot = pSym '.'
and then:
*Main> test pDate "3.4.5"
Loading package syb-0.1.0.2 ... linkin
I had been using Parsec to parse VCD files, but needed to lazily parse
streaming data. After stumbling on this thread below, I switch to
polyparse.
What a great library! I was able to migrate from a strict to a
semi-lazy parser and many of my parse reductions didn't even need to
change. Thanks
