We ought to at least try to avoid clear and obvious conflicts between
new and existing syntax.
Using `:=` is even worse than `=>`, and `=:` is just *begging* to
confuse newcomers "why do we have THREE different assignment symbols?"
You can't have it both ways. Either you re-use `:=`, or you add a third
symbol.
(There would be no actual conflict with the walrus operator.)
