thanks for any enlightenment regarding this.

Inside a function things happen in order, top to bottom, 
including declarations (you can only access local variables after 
they are declared, and nested functions work like local 
variables).

In a declaration, order is less important.

For recursive nested functions it can sometimes help to put a 
declaration inside a function:

void main() {
  // order matters here, in function
   struct Holder {
       // order doesn't matter in here, in decl
    }
  // order matters again since functions run in sequence
}
