Start "modernizing" the code base; old code is based heavily in the
Smalltalk style, where everything that doesn't return a different object
returns self. This can be useful, but it isn't what is usually done these
days. Also, add type information (which didn't exist in "the old days" --
an object was an "id", not a "Foo *") to help with debugging.
However, it still won't work (no gorm, commented code, ...).
Borrow an old implementation of the Storage class until I figure out just
what it's being used for.
