[Haskell-cafe] FAQ: Why no interactive definitions?

[Greg Woodhouse]

In neither GHCi nor Hugs (so far as I know) is it possible to
interactively enter definitions. coming from Scheme, this was a bit of
a surprise, as I'm used to being able to enter, say

(define mysquare
    (lambda (x)
      (* x x)))

Is this just a matter of the feature not being implemented, or is there
a deeper reason for this?
