You can alias symbols. You can't alias statements, and mixins are always
explicit. Now, you could have a function that returned what you wanted to
mix in so that you just did something like

mixin(use_local_function());

and have use_local_function return whatever code it is you want to mix in,
but you can't just do something like

use_local_function;

and have it work. That would be more like a macro system, and D doesn't have
that. We have string mixins and template mixins, but those are both
explicitly mixed in.
