Hello,

swishParse :: String - String - SwishStateIO (Maybe RDFGraph)
swishParse fnam inp =
do { fmt - gets $ format
; case fmt of

otherwise is not a keyword. It is just defined as a normal function

Hi Vasili,
This isn't really a shadowing/redefinition issue. Here's
a perfectly legitimate snippet that compiles fine:
f 0 = 0
f otherwise = 1+otherwise
Redefinition is when you have:
g = let otherwise = not in x

In you have an odd number of items, the middle one will be at position

When Haskell runs it's type checker, it tries to guess the type of
each function. Thats why you can write:
map (+1)
and it knows that you're talking about a function of type:
Num a = [a] - [a]
Another thing, called 'defaulting' resolves this, but you didn't ask
about that, so I won't

I really dislike this error message, and I think the terms are
ambiguous. I think the words 'expected' and 'inferred' apply equally
well to the term, and the context in which it has been found. Both of
the incompatible types were 'inferred', and 'unexpected' is a property
of the combination, not a

Frankly, I highly doubt it makes any difference
Whoops, you're right.
Interestingly, the shadowing warnings vary between
the 2 examples I gave, i.e. shadowing within
'function definition' vs 'binding group'.

How about 'calculated' vs 'user-imposed' (or even, 'explicitly-
