I define a function foo in which it calls an auxiliary function bar,
which is not yet defined, and a compiler exception is raised claiming
unable to resolve symbol bar.
Is there a way that I can define the functions in any order I want,
without taking care of defining the auxiliary function
not yet.
But you can just declare the function, before implementing it:
(declare bar)
(defn foo [] (bar hello))
(defn bar [man] (println hello man))
Be aware that if you need to typehint bar, you'll also need to type
hint the bar declaration, so that the compilation of foo can use this

Yeah, I don’t really like the underscores either. But I have to work

people to bring in their input.

I think using a naming convention isn't a good idea, especially when
you have a rich macro system like Clojure. I'm actually going to be
talking about using a reference to handle things like this in my next
episode. For now, you can take a look at my definference macro here:
Could you explain more what you mean? For instance, how are macros
related to these questions? This just has to do with informal naming
conventions, in the same matter as *e or *print-dup*. Are you talking
about that it’s possible for naming conventions to interfere with
macros that interpret
You can also do stuff in the middle of a let;
(let [a vala
b valb
_ (do-something-with a b)
c (some-fn a b)
d (some-fn a b)
_ (do-something a b c d)
e (fn ...)
f (fn )]
(and-whatever-else))
Here _ is just some arbitrary unused variable.
Note that
Ah, yes, it is a. (The only thing that I anticipate a computer would
use this for is different syntax highlighting. Actually, can any
Clojure editors change symbols’ colors based on if they match a
pattern like *a*?)
Because Daniel Warner and Jarkko Oranen both said they think

Ah, case a is simpler, and I retract my macro suggestions.
As to you question about editors, I know that it's possible to adapt
emacs clojure-mode the change colors based on a regex. That's how it
knows to color something pink for a fn in clojure.core, and green
for a fn in the standard library
