Plugins that implement an eval test will need to call this, so that
SpamAssassin calls into the object when that eval test is encountered.
See the B<REGISTERING EVAL RULES> section for full details.
+Since 4.0, optional $ruletype can be specified to enforce that eval function
+cannot be called with wrong ruletype from configuration, for example user
+using "header FOO eval:foobar()" instead of "body FOO eval:foobar()".
+Mismatch will result in lint failure. $ruletype can be one of:
+
+ $Mail::SpamAssassin::Conf::TYPE_HEAD_EVALS
+ $Mail::SpamAssassin::Conf::TYPE_BODY_EVALS
+ $Mail::SpamAssassin::Conf::TYPE_RAWBODY_EVALS
