+Due to this bug fix, functions using the C<(*)>, C<(;$)> and C<(;*)> prototypes
+are parsed with higher precedence than before. So in the following example:
+
+  sub foo($);
+  foo $a < $b;
+
+the second line is now parsed correctly as C<< foo($a) < $b >>, rather than
+C<< foo($a < $b) >>. This happens when one of these operators is used in
+an unparenthesised argument:
+
+  < > <= >= lt gt le ge
+  == != <=> eq ne cmp ~~
+  &
+  | ^
+  &&
+  || //
+  .. ...
+  ?:
+  = += -= *= etc.
