Description

§

(environment list_1 ...)

This procedure returns a specifier for the environment that results by starting with an empty environment and then importing each list, considered as an import set, into it. (See section on libraries for a description of import sets.) The bindings of the environment represented by the specifier are immutable, as is the environment itself.
