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
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
