Yes, the error messages indicate that GHC is parsing the expression as

   (take) - (1 [1,2,3])

and consequently complains that

   take :: Int -> [a] -> [a]

is not a number (i.e. an instance of class Num) and that it can't
interpret the inferred type of

   1 :: [t] -> (type of take)

as a Num .
