Friends in D, the easy way!

[Mr.Bingo]

These go in the module you want allow access to the outside world 
just as if they were in the same module!

auto Setter(string name, alias O, T)(T t)
{
	mixin("t."~name~" = O();");
}

auto ref Getter(string name, T)(T t)
{
	mixin("return t."~name~";");
}



x.Setter!("privateFieldName", { return value; }); // 
privateFieldName = value;
x.Getter!("privateFieldName"); // = privateFieldName


You can think me now... or later, which ever you choose! I hope 
there is no SOLID henchmen here!

Of course, these should be used only between modules that are 
tightly coupled... This can happen when a derived class needs 
access to it's parent as if it were in the same module but the 
modules are split only for parsing.
