I would like to have a macro which I'll call def-foo. Def-foo will create a function, and then will add this function to a set.

So I could call

(def-foo bar ...)

(def-foo baz ...)

And then there would be some set, e.g. all-foos, which I could call:

all-foos
=> #{bar, baz}

Essentially, I'm just trying to avoid repeating myself. I could of course define the functions in the normal way, (defn bar ...) and then write the set manually.

A better alternative, and simpler than the macro idea, would be to do:

(def foos #{(defn bar ...)    (defn baz ...)} )

But I'm still curious as to whether there is a good way for the macro idea to work.
