Well, how do languages where assignment is an expression returning the

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.
