HsParser is confused by the combination of qualified names and
identifiers starting with underscores. For example:
module M where
_f _ _ = 0
x = 0 `M._f` 0 -- parse error at '.'
y = M._f 0 0 -- parses as M . (_f 0 0)
I have tested this only for GHC 5.02. For what it's worth,
that the '=' is located at the column marked by the ^.

why this example fails to parse too:
f x = do

where y = x

HsParser fails on any of these 6 examples:
data Data = A {
x :: Int
}
f1 x = let {
s = x
} in s
f2 x = do {
x
}
f3 x = case x of {
_ - 12
}
f4 x = s where {
s = 12
}
f5 y = A {
x = 45
}
The problem seems to be the
