Neither is easy to read. Go to your nearest non-programmer unit,

I agree with Paul here. I hated the int: because it had nothing to do
with indexing. I could reluctantly accept index: -- but it will not
help the intended audience. Only programmers understand things like
indices, keys, etc. What is worse, is that it builds a bunch on
un-pythonic syntax, which will get in the way of learning python later.
Let ZPT handle the simplest things, and escape to python as needed.
Lo, ZPT has not even a proper expression syntax. All that is going on
here is creating a syntax for some extremely limited special cases, a
really non-standard syntax. And, the syntax depends on having some
python programmer create the dictionaries or sequences that are being
That to me, is the fatal flaw. It is hard to argue, on one hand, that a
python programmer is available to you whenever you need a sequence
created, and on the other hand, that he is no longer there to
consult/hand work off to when a simple expression is needed.
