Believe it or not, that particular caching has been there for a long time
now.  It has always bothered me but I didn't know why, and now I know why.
:-)  This specific case could be corrected, though.

This happened because Document now has a __call__() method.  It didn't
before.

I would try <dtml-if expr="_.getitem('bio', 0)">.  Ugly but it works.
ZPT, which is coming along very well, is designed from the start to
provide clean alternatives to expressions like that.
