Double EL indirection in STL?

[Lee Crawford]

I'm trying to determine if there's a way to express the equivalent of:
  
  ${${x}}

in the STL EL. This yields an exception in the current beta release of the
STL. 

For instance, I'd like the following: 

    <c:set var="x" value="y"/>
    <c:set var="y" value="1234"/>
    <c:out value="${${x}}"/>

to yield: 

    1234

obviously I can use nexted pageContext.findAttribute() calls to do this:

  <c:set var="x" value="y"/>
  <c:set var="y" value="1234"/>
  <%= pageContext.findAttribute ((String) pageContext.findAttribute ("x"))
%>

but I'd like to be able to do this from the EL. 

Cheers.
