--- Comment #22 from Nikos Platis <nplatis at freemail dot gr> 2012-04-26 14:33:45 UTC --- I am sorry if my knowledge on this issue is limited, but if I put t() and f() in namespace glm (re. the code in comment #20), should this compile? (That is what you comment #19 implies). Actually it does not.
