It's open source so in theory anything is possible, but there's no 
built-in support for that.

If you wrap the assignment in parens the result is made visible, e.g.

(x <- 8)

will print if you enter it in the console.  (It won't print if it's a 
line in a function; there you need an explicit call to print().  Only 
the value returned at the top level is eligible for auto-printing.)
