requiring an empty .clj without an alias should fail as with an alias

Question

if file a/b/c.clj is "empty"

it creates an empty ns: (and does not fail) when doing

(require '[a.b.c])

while when using ":as" it fails correctly with error:

(require '[a.b.c] :as c)

Syntax error compiling at ... ; namespace 'a.b.c' not
found after loading '/a/b/c'
