Great ! Don't know if i can help (time), but if you have a road map or
something like that, i would be happy to contribute.

Variable nature and scope (kind of non-mutable that you can overwrite ?),
but someone could tell me this a feature :-). Perhaps i've miss something,
but look what i need to do to retrieve a value incremented inside a forEach
loop:

<jx:set var="globalvars" value="${java.util.HashMap(5)}"/>
<jx:set var="dummy" value="${globalvars.put('a_count', 0)}"/>
...
<jx:set var="a_count" value="${globalvars.a_count}"/>
<jx:forEach begin="1" end="3" varStatus="i">
   ...
   <jx:if test="#{$node/@path != ''}">
      ...
      <jx:set var="a_count" value="${a_count+1}"/>
      <jx:set var="dummy" value="${globalvars.put('a_count', a_count)}"/>
  </jx:if>
</jx:forEach>

<jx:out>this is my count: ${globalvars.a_count}</jx:out>

It would be easiest (and efficient) to do
<jx:set var="a_count" value="0"/>
<jx:forEach begin="1" end="3" varStatus="i">
   ...
   <jx:if test="#{$node/@path != ''}">
      ...
      <jx:set var="a_count" value="${a_count+1}"/>
</jx:forEach>

<jx:out>this is my count: ${a_count}</jx:out>

the fact that "set" make always a "new define" is quite annoying at first
glance (functional programming ?).

Regards.
