Yes, I suppose it might be useful in some cases. The operator would have to
be something other than the '+' sign, though, since JSTL wouldn't know what
to do with an expression such as 'x + y' if both 'x' and 'y' were numeric
strings. (Should it add the numbers or concatenate the strings?)
You can still solve the problem you suggested, though, by using an
intermediate:
<c:set var="temp" value="${x}${y}"/>
<c:if test="${temp == 'asdfasdfsdf'}>
...
</c:if>
