Specialized Structure Slots

numeric slots specialized structure slots

Structure slots declared by the :type defstruct slot option to have certain known numeric types are also given non-descriptor representations. These types (and subtypes of these types) are supported:

(unsigned-byte 32) single-float double-float

The primary advantage of specialized slot representations is a large reduction spurious memory allocation and access overhead of programs that intensively use these types.
