Hey Mamun,
Your problem is that your ^{:test true} metadata isn't being applied
to your functions, as you might expect, but rather to the var that is
pointing to the function. You can see this in the following (#' is a
shorthand to get the var rather than the thing it contains).
user=> (meta f1)
nil
user=> (meta #'f1)
{:arglists ([]), :ns #<Namespace user>, :test true, :name f1, :line 1,
:source "(clojure.core/defn ^{:test true} f1 [] (println \"Call f1
fn\"))\n", :file "NO_SOURCE_PATH"}
You can solve this in two ways:
1) Have `f*` contain a list of symbols, then use `resolve` [1] to get
the vars. Then the definition of `f*` becomes `(def f* (list 'f1
'f2))`
2) Have `f*` contain a list of vars
Once you have the vars then you can use `(-> form meta :test)` to
access the value for the :test metadata.
Due to the way vars are implemented, calling `(form)` when `form` is a
var will actually call the function that `form` is pointing to, so the
earlier function call should continue to work.
I hope that helps!
Carlo
