The Python-independence of TALES is a goal for the spec, not for 
individual implementations.  If your implementation would work better 
without path expressions, and with Python expressions as the default, go 
for it!  I presume that you also aren't concerned with placing security 
restrictions on the code, so eval() is fine.
