Summary: Incorrect Type Inference?

Initial Comment:
If the function 

func1 = \x -> map (*x)

is saved into a file, and then imported to ghci 
(v6.4, windows), the type becomes 

Integer -> [Integer] -> [Integer]


However, if I do 

:t \x -> map (*x)

the result is:

\x -> map (*x) :: (Num a) => a -> [a] -> [a]

which seems correct.

The monomorphism restriction applies to definitions in
source files, but not to expressions supplied as the
argument to :type in GHCi.

Not a bug, sorry.
