Summary:
efl_new(CLASS), i.e., without initializers, never worked before.
The problem is the dangling comma: efl_add_ref(klass, NULL, );
Fortunately the C preprocessor concatenation operator # # has a special
case just for this occasion: When you do A ## B, and A is a comma and B
is empty, it removes also A.

This trick is already in use in several other EFL headers using variadic macros.
