In B, use typeglob aliasing instead of subref to typeglob assignment.

Typeglob aliasing saves just about 1.25K, because fewer internal structures are
created. In the general case the behaviour of the two differs, but as the
only package variables of these names are subroutines, and we are within our
own namespace, there is no difference here.
