This code fails to compile with a forward reference error:
auto descendantsOf(Node* node)
{
return join( node.children, join(node.children.map!
(descendantsOf).array) );
}Obviously, while functions can be internally recursive and call themselves, it appears that they can't use themselves as template parameters. The Y combinator still blows my mind, so does anyone have any ideas about how I could rewrite this without making it super ugly?
