< and > used as brackets is completely brain dead. Here a little 
example in C++ showing why

fon< fun< 1 >>::three >::two >::one

what doas it mean? (i.e. how is it parsed).

Answer: it depends. It doesn't parse the same under C++98 or 
C++11.

fon< fun< 1 >>::three >::two >::one    // in C++98
           -----------
      -----------------------
-----------------------------------

and

fon< fun< 1 >>::three >::two >::one    // in C++11
      --------
---------------------
----------------------------
-----------------------------------

and to avoid this catastrophic parsing nightmare, D chose a 
syntax that is not ambiguous.
