It was just a fun experiment, really. :-)  I became a little discouraged about 
updating it because of the migration to unicode.  <string.h> is an old friend 
that's hard to part with.

In Zope 2, the main bottleneck isn't the TAL interpreter, it's the expression 
evaluation.  Even simple TALES expressions in Zope 2 are fairly expensive.  I 
don't yet know how Zope 3 compares.
