Description

Implements SICStus-Prolog compatible attributes on variables, via mapping to native ECLiPSe attributes (one ECLiPSe attribute for each module that defines SICStus attributes).

Implements the predicates

get_atts(-Var, ?AccessSpec)
getting attributes
put_atts(-Var, +AccessSpec)
setting attributes
and allows the user definition of the hook predicates
verify_attributes(-Var, +Value, -Goals)
pre-unification hook, called as ECLiPSe's pre_unify handler
attribute_goal(-Var, -Goal)
allows to define an interpretation of the attribute as goal. If defined, it is also used as the print-handler for attributes.
ECLiPSe's toplevel makes no attempts to invoke any hooks.
