LispWorks provides form parsers name-only-form-parser, single-form-form-parser and single-form-with-options-form-parser. You can use single-form-with-options-form-parser as the parser for
my-defun
definitions (see Dspec aliases), like this:
(dspec:define-form-parser (my-defun
(:parser dspec:single-form-with-options-form-parser)))
This allows the Editor to locate definitions like:
(my-defun (foo x y)
(+ x y))
You can identify the form parser defined for a dspec class using get-form-parser.
