There are a number of ways to use Functional Developer's language extensions in your applications.
A few extensions have become part of the dylan library. You can read about these extensions in Section 1.3 on page 2.
The majority of the extensions are in the common-extensions module of the common-extensions library. That library also exports a number of smaller modules that contain other basic facilities such as simplified formatting (simple-format), pseudo-random integer generation (simple-random), and object finalization (finalization).
Functional Developer provides a convenience library, common-dylan, that combines the dylan and common-extensions libraries to provide a convenient "dialect" of Dylan, exported from the module common-dylan:
define library common-dylan use dylan, export: all; use common-extensions, export: all; export common-dylan; end module; define module common-dylan use dylan, export: all; use common-extensions, export: all; end module;
