Now that clojure 1.9 is out, will future releases be 1.91, 1.92, etc?
Or, are talks in place for a clojure 2.0?
If there is discussion of clojure 2.0, what would that look like?
Clojure running on graal, clojure (the people behind it) doing some other
fantastically amazing thing?
Just curious
It says that a number cannot be cast to a function.
(3 4)
The number 3 is not a function, thus the reason for the error.

One more thing, is it cheap to hash immutable maps vs mutable ones?

I was wondering something...
Would (= {:x 1} {:x 1}) be just as fast as (= 1 1) since maps are
immutable? The idea is that since clojure data structures are just values
can they be compared much faster than there mutable counter parts? Thanks.

I am just using this as a learning exercise, I do not need to be lectured

Say I have two data structures..

I want to update them like so...

enemies and then bullets; would I use refs here or would
Also, you can use straight up java as well inside of loops. I, sometimes,
will write a static method, dump the clojure data strcuture over to java,

I use mutation generously inside of functions. I do not consider that

Let me rephrase your question to show you something...
Should I learn LISP in order to learn LISP...
Clojure is a dialect of LISP as is common lisp; when you learn Clojure you
are learning LISP. Clojure "has its opinions" about how to do its list
processing, however, all other list processing

The people is not a sufficient answer(I am sure you knew that but I had to

1. Homoiconic syntax
2. meta programming facility(macros in the case of clojure but other LISP's

These two "powers" are what draws so
