* DeferWrapper didn't cache the result of the expression like ordinary vars do.
This was intended, though you couldn't know that since I never documented this. Consider the following terrible example:
<div tal:define="xis defer:string:x is $x"> <p tal:repeat="x python:range(3)" tal:content="xis"></p> </div>
This should evaluate to:
<div> <p>x is 0</p> <p>x is 1</p> <p>x is 2</p> </div>
Why?? I don't remember why I wanted this behavior; it was an experiment, and I can't find any code of mine that uses it.
