Apart from going a bit cross-eyed from seeing clojure-as-java code
from the first time, I get it :-)
Thanks Chas, I'll give it a try and let you know how it goes.

Hello fellow Clojurians,
yesterday I was watching Neal Ford's brilliant world domination video
and it got me again thinking about idea I've got for some time.
With the advent of online learning initiatives like Stanford, MITx,
and many others I think it would be great to create Clojure course.

Sounds like you should build a simple abstraction layer over atoms instead
of trying to use them directly? Or provide a new data binding / propagation
protocol that avoids the limitation of atoms? For data binding you most
definitely always want to receive the old value in my experience.

That's the point. Empty lazy sequence doesn't work, but not empty lazy

Not that it's pertinent, but a parsec is 31 trillion kilometers.
Given the single-threaded nature of JavaScript I don't see how
future-call or agents could be implemented.
There are analogous constructs in a single-threaded, async-callback world.
In particular, many Javascript libraries have a concept of promises and
futures for managing the async callback

Hi all,
I am trying to implement a function that splits any given sequence on a
subsequence. I would like it to behave like this:
user (split-at-subsequence [5 6] (range 10))
((0 1 2 3 4) (7 8 9))
user (split-at-subsequence [5 7] (range 10))
((0 1 2 3 4 5 6 7 8 9))

partition-by is lazy in that it only splits its argument into as many subseqs
as requested; the subseqs themselves are not lazy. So when you partition-by the

request the infinite third subseq thereof, partition-by won't

I'm arguing that IMHO, the atom+watcher abstraction is not rich enough

Atoms have the watcher list natively built into their datastructure.
But the watcher abstraction is too simple to do anything beyond
syntactic sugar.
