+== No implicit :main subs ==
+
+=== Description ===
+
+PIR programs will be required to have a sub marked :main.  Previously if no sub was marked :main, the first sub would be used.
+
+=== Rationale ===
+
+Requiring a sub to be explicitly marked with the :main modifier makes PIR less magical and surprising and will make it easier to discover how a piece of PIR code works.
+
+=== Replacement ===
+
+Pick a sub and mark it with the :main modifier:
+{{{
+.sub 'start_here' :main
+  do_stuff 0, 1, "bananas"
+.end
+}}}
