Hi Joe,

The FuncDeclaration node contains all the information for that.
For example, you can access fd.parent to see if the function is
declared at top-level (in which case, the parent is going to be a module declaration ) or if it is a nested function (in a class, in a struct, in a function). Every AST node contains information about the position in the AST, all you have to do is find how to get that information: which field to access or which
member function to call.



Follow up question...

Why is *.parent always null?

extern(C++) class MyVisitor(AST): ParseTimeTransitiveVisitor!AST
  override void visit(AST.Import i)
    assert(i.parent is null); // always true

  override void visitFuncBody(AST.FuncDeclaration f)
    assert(f.parent is null); // always true
