Should be a hyperlink?

Attempted to correct the reference to include a hyperlink. Do not know if OK, as I do not know how to test it localy. In any case, the title of the referenced page is actually "Metaprogramming", so maybe the reference title should also be updated?

Same as a previous "correction" - I suspect the current state is wrong, but am not sure of the correct state. (The page carries a different title as the title mentioned.)
