   An interesting side-note here is that objects with types #2baa,
#2bcc, #2bee, and #2c10 all appear as External on the stack, and have
TYPE 27. They can be recognized in a type switch as <1ah>, <1bh>,
<1ch>, and <1dh>. They are Library Data objects, i.e. a type followed
by a 5-nibble size word, followed by the data, and evaluate to
themselves.
