No. What you can enter at the prompt are either Haskell expressions or Hugs 
commands (use ':?' to seem them all). 'test :: Int' is an expression, but if 
you haven't loaded any script, test is undefined, and Hugs is telling you 
that. 'size = 12 + 13' is not an expression, but the definition of the value 
of 'size', and you can't do this on the prompt. Put that into a file and load 
it via :l, and this should make Hugs (and you ;-) happy...

Cheers,
   S.
