If skip is a regexp, then exporting matching that regexp are ignored. If it is a symbol, then that export is ignored. If it is a list of symbols and regexps, then any exporting matching any of the symbols or regexps are ignored. If it is a function, the function is treated as a predicate and passed each export of the module. If skip is #f, no exports are skipped.
