Yet another chainsaw massacre.
One of the most obnoxious annoyances with C++ metaprogramming
is the need to insert `typename` and `template` qualifiers into
most definitions, to help the compiler to cope with the syntax,
which is not context-free.
The recent standards adds several clarifications, so that most
of these qualifiers are redundant now, at least at places where
it is unambiguously clear that only a type can be given.
GCC already supports most of these relaxing rules
(Clang unfortunately lags way behind with support of newer language features...)
