Two significant releases have just been pushed!

Metalang99 ships with a new collection, sequences, and the macros
`ML99_boolMatch` & `ML99_boolMatchWithArgs` to match a boolean value.

The new version of Interface99 features default method implementations
and reduced syntax boilerplate:

    #define State_IFACE                     \
        method( int, get, void *self)       \
        method(void, set, void *self, int x)

    interface(State);
