As you point out, symbols in edn have no inherent meaning; it's entirely up
to how you interpret them. However, if you saw the symbol
"clojure.core/conj" in an edn file, then the chances are that it's intended
to refer to a Clojure function. Similarly, the symbol "PI" likely refers to
the mathemati
Thank you for responses.
The last two arguments do not resolve the doubt, however:
1. symbols also implement IFn:
(require 'clojure.edn)
('a (clojure.edn/read-string "{a 1 b 2}"))
=> 1
2. EDN does not specify any evaluation model, so how can a symbol designate
something "in isolat

I think James talking about resolution of values when he said "designates",
not "the value bound to a key in the map." In other words, the keyword
:email resolves to the keyword :email, whereas the symbol clojure.core/vec
resolves to a function.
Keywords-as-keys give you some benefits when you'
Regarding the idea that a keyword is an identifier that designates itself,
while a symbol is a keyword that designates something else.
Keys in config file map do not designate themselves, they designate the
corresponding map values.
{username "vasya" email "a@b.c"}
Here the EMAIL symbo
In edn, a keyword is an identifier that designates itself, while a symbol
is a keyword that designates something else.
This means keys in a map should generally be keywords, unless they identify
something beyond themselves. For example:
{:profiling/function-count {clojure.core/vec 10}}
On Th
My personal opinion is to prefer keywords, and prefer less preprocessing of
the configuration before the program uses it.
If it gets to a place where the configuration changes a lot, and a
"natural" (read: clojure-like) expression of the configuration in EDN has
either a lot of redundancy, or bits
I'm working on a config file format in EDN, and in doubt: should I use
keywords or symbols as map keys.
After all, the colon is an extra keyboard press - an extra effort for users.
As EDN parser doesn't evaluate expressions, there is no need to quote
symbols when using them as EDN map keys (unl
