Recursive instantiations.

You are trying to instantiate ComponentView<>, which, for some reason, requires
Array<> to be complete. Completing Array<> requires instantiating the prototype
of Array<>::comp() which, in turn, asks for ComponentView<> instantiation.

This does not happen with AltComponentView<> since its instantiation is not
required to complete Array<> so there is no loop.


Totally unrelated:

typedef Array This_t;

as in: you don't need the typedef.
