What is the point of what exactly? Of yet another lambda notation? Of round
brackets? Of my post? :)

Anyway, there wasn't much of the point besides demonstrating that something
like this is easily implementable and could have some practical use - may be
outside the MPL as well. After all, people has been complaining about "ugly
template brackets" for years ;).

Yes, I needed a separate scope to put things into to avoid conflicts as all
new lambda's arguments are metafunction classes, not metafunctions. It (the
namespace) doesn't carry much of intent besides that :).

FWIW, I am not moving on to anything. I coded up the above in ~1 hour as a
proof of a sudden idea that seemed like a novel and viable technique.
