Squeak 3.9 still supports _ for assignments, it just prints it as _
and not as an arrow (which confuses almost every newbie).

Automatic _ to := is not that simple, not every _ is an assignment and
there are some live methods, which you can not just change. There is a
script for this which handles most cases.
