I was referring to the use case as to why we should have the 
ability to get scoped variables from the initiation point.
Example:

void func(int i) {
     bool b;
     macr {}
}

macro foo (Context context, Ast!(string) str)
{
     writeln(context.scopeVariables!int("i"));
     writeln(context.scopeVariables!bool("b"));
     return "";
}
