An aggregate type is a struct, union, class, interface, or enum whose base type
is one of those. It would be helpful to document this; it isn't obvious merely
from the name that all of those are "aggregates" but not array slices (pointer
and length) or delegates (function pointer + context pointer) or static arrays
or associative arrays.

If there is some precise sense of "aggregate" that makes it obvious what this
category means it would be useful to insert that but I'm not sure if I see it.
All aggregate types are things that are capable of having `alias this` but I'm
not sure if that's related to the definition or incidental.
