namespaces are a general need in programming
objects orientation has its niches where it actually makes sense

The Zen of Python, by Tim Peters
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!
>>>
Objects aren’t mentioned at all.
Namespaces are, and that statement is oh so true.

J is poor at compound expressions that operate on an object.
J's object model is about encapsulating administrative boundaries --
it was not designed to replace primitives. J's objects / locales allow
people to work while minimizing the need to contend with other people
on issues of namespace collisions.
Objects for everything works, of course (see also: turing equivalence)
-- but it tends to be inefficient for many things (and have required
massive efforts to approach J's level of efficiency on arrays and
array operations).
(Personally, I would much rather concern myself about physically
useful interfaces and mechanisms than focus on re-inventing a wheel
which has already been re-invented countless times.)
That said, dictionaries with composable functions might eventually
lead to an object-like mechanism which could compete with locales.
And, I guess this was still an interesting observation.
Thanks,
