> I think it is not fair to say 'big rush'. What happened is as follows: Sorry but I was a remote participant. You certainly had a long discussion before, perhaps on other matters, RDF alternative, the various semantics etc. From IRC thogh, I did not get the impression that thre has been a long discussion about this specific point *to switch back to full typed syntax*, which has important implications, in particular when I recalled my earlier email at the F2F, I did not get any feedback before the vote. Hence my feeling of rush. > However, as Boris made us discover, this structure only works if the functional syntax becomes fully typed, too I missed that point, not sure it's explicit on IRC, it might be worth to make it clear for everybody.
