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)"

This should evaluate to:

  <p>x is 0</p>
  <p>x is 1</p>
  <p>x is 2</p>

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.

That's an interessting use case. Do you want me to keep the code and make up a new expression? I'm thinking about "lazy:".
