Attributes protected and package cause imports to be public in certain cases.

--- main.d
module main;

void scope1()
{
    import pkg.regular_imports : a; // Error: not found
    import pkg.regular_imports : b;
    import pkg.regular_imports : c;
    import pkg.regular_imports : d;
    import pkg.regular_imports : e;
}

void scope2()
{
    import pkg.selective_imports : a; // Error: invisible
    import pkg.selective_imports : b; // Error: invisible
    import pkg.selective_imports : c; // Error: invisible
    import pkg.selective_imports : d;
    import pkg.selective_imports : e;
}

void main() {}

--- pkg/regular_imports.d
module pkg.regular_imports;
private import pkg.a;
protected import pkg.b;
package import pkg.c;
public import pkg.d;
export import pkg.e;

--- pkg/selective_imports.d
module pkg.selective_imports;
private import pkg.a : a;
protected import pkg.b : b;
package import pkg.c : c;
public import pkg.d : d;
export import pkg.e : e;

--- pkg/a.d
module pkg.a;

Doesn't apply to selective imports.
Doesn't happen when modules a..e exist at the top level, not part of any package.
