Well, how do languages where assignment is an expression returning the assigned value make their REPLs work? I'm sure they don't inflict that on their users, so it's certainly a solvable problem.
I can't think of any such language that has a REPL offhand, but here's a possible solution:
x := expr # doesn't print anything
Ugh! The only reason I would bother typing the : in a top level assignment would be to get the print without having to retype the name, as in
x = expr x
I consider echoing top-level interactive assignments to be a feature of the proposal.
