Handlers are compared through their names (through the mandatory +name slot). A hook can not contain multiple handlers with the same name. + +@item A special provision is taken for “setters”, handlers that are meant to +set a given place to a given values. Such handler objects can be compared and +identified uniquely. + +@end itemize\n") + (license license:expat))) + +(define-public cl-nhooks + (sbcl-package->cl-source-package sbcl-nhooks)) + +(define-public ecl-nhooks + (sbcl-package->ecl-package sbcl-nhooks)) |
