I think this is a bug, but I want to get opinions on this.  It appears
variables defined by item="" in an iteration are staying in scope for the
rest of the query evaluation.
For example:
If I call a select passing in a param map of "bunchIDs" -> a List of
Integers, let's say {1,2}, then this XML:

*  <if test="bunchIDs != null" >*
*     <foreach item="bunchID" collection="bunchIDs" open="AND nd.bunch_id
in (" close=")" separator=",">*
*       #{bunchID}*
*     </foreach>*
*  </if>*
*  <if test="bunchID != null" >*
*     AND nd.bunch_id = #{bunchID}*
*  </if>*

will produce the where clause

*AND nd.bunch_id in (1,2) AND nd.bunch_id=2*

I don't think bunchID should be defined anymore when it runs the evaluation
*<if test="bunchID != null" > *happens.
