Using function_exported? is definitely the way to go. Thank you, I did not know about that function!
As for using apply: It would end up in the documentation as well:
See f.e. here:
Validated/parsed by calling
&Confy.Parsers.boolean/1.
this would then become
Validated/parsed by calling
&apply(Confy.Parsers, :boolean, [&1]).
which is not nearly as nice.
Thus I really am looking for a way to construct &SomeModule.foo/1 where foo is a dynamic value.
If there is no way around sing Code.eval_quoted then that is fine, but I did want to check 
.
