The point of Armin's original msg in this thread was that direct replacement
can have different semantics. Applying a transformation (via list()) is a
different story, although I expect someone obsessed enough could concoct an
example that worked differently, because genexp guts truly live in a
different scope than listcomp guts (e.g., play games with locals()).
