22.5 Structures

[FIXME: this is pasted in from Tom Lord's original guile.texi and should be reviewed]

A structure type is a first class user-defined data type. A structure is an instance of a structure type. A structure type is itself a structure.

Structures are less abstract and more general than traditional records. In fact, in Guile Scheme, records are implemented using structures.
