Intern-list

Generate a list of symbols in some package.

Examples:

(intern-list '("FOO" "BAR"))           --> (acl2::foo acl2::bar)
(intern-list '("FOO" "BAR") 'str::foo) --> (str::foo str::bar)

(intern-list x &optional (pkg ''acl2::acl2-pkg-witness)) is a macro that takes

• names, a list of strings that will become the symbol-names of the new symbols, and optionally
• pkg, a symbol that is used as a package indicator, as in intern-in-package-of-symbol.
