:anon-fn-naming-policy

Determines how Closure Compiler assigns names to anonymous functions in assignments and declarations. Defaults to :off.

• :off - unnamed
• :unmapped - named based on left-hand of assignment (after possible renaming)
• :mapped - short unique name generated and mapped to left-hand of assignment

:anon-fn-naming-policy :unmapped ;; <-- assign names to anon functions

(It is unclear how short names from :mapped are mapped back to their original names during debugging)

(ns foo.core)
(def x (fn [] ...))

Compiles to the following when :off:

foo.core.x = (function (){ ... });

Compiles to the following when :unmapped:

foo.core.x = (function foo$core$x(){ ... });

:mapped seems to compile to the same as the above.
