+    [perl #105924] require 1 << 2
+
+Setting PL_expect after force_next has no effect, as force_next
+(called by force_version and force_word) picks up the current value of
+PL_expect and arranges for it to be reset thereto after the forced
+token is force-fed to the parser.
+
+The KEY_require case should be setting PL_expect to XTERM (as it
+already does) when there is no forced token (version or bareword),
+because we expect a term after ‘require’, but to XOPERATOR when
+there is a forced token, because we expect an operator after that
+forced token.
+
+Since the PL_expect assignment has no effect after force_next, we can
+set it to XOPERATOR before calling potentially calling force_next, and
+then to XTERM afterwards.
+
+Loop exits had the same bug, so this fixes them all.
