work for a lot of contexts. BTW, the ast for "left |isa| right" is
Bitor([Name('left'), Name('isa'), Name('right')])

involving the specal op names would be ignored.

As expected, or do you want to define different semantics?
You still need to spell len(a) in the slice somehow to indicate
beond the top. E.g.,

Zbrxlist(['a', 'b', 'c', 'd', 'e', 'last', 'end', 'final'])

your progammer.agility value can increase markedly with a little study ;-)
E.g., a name like monsters.random_elf could live right
alongside PIRATE and return one a randomly selected elf from a an internal list
of elves or via random selection from a list of elf names defined at the same
level as PIRATE, etc. etc. You could also dynamically configure these guys
according to distance to food and time since last meal, and if you are
carrying food, etc.
With suitable classes you could put instances in various "spaces" defined
by other classes, that define geometric or social or other interactions.

The trick is to keep in mind that there is some abstraction that is
being represented in various ways, and make allowances for people's
saying "hex" when they mean the binary that the hex (characters
matching [0-9A-Fa-f]) representation is representing, and similarly
with other abstractions (e.g. binary ;-) and their representations (e.g.,

I agree that the OP's proposal is not a core language matter.
Perhaps this is another PEEP candidate (i.e., a "Python Evironment Enhancement
Proposal"
to put in a "PEEP" application/tools/environment-oriented clone of the PEP
process).
Maybe a PEEP top page in the wiki with l

I usually prefer %r over %s for debug prints
if debug: print "v=%r" % (v,)
since it represents (repr's ;-) the v t
