This isn't so bad because a deprecation is still emitted when the function is
used.

But still, it should probably be emitted on a selective import too.

//////////////// a.d ////////////////
deprecated int var;
deprecated void fun() {}
/////////////// test.d //////////////
// import a : var; // OK, deprecation
import a : fun; // No deprecation?
/////////////////////////////////////
