6.1.2.1.7 The for-as-package subclause

In the for-as-package subclause the for or as construct iterates over the symbols in a package. In this syntax, a compound preposition is used to designate access to a package. The variable var takes on the value of each symbol in the supplied package. The following loop keywords serve as valid prepositions within this syntax:

In effect

being {each | the} {symbol | symbols | present-symbol | present-symbols | external-symbol | external-symbols} {in | of}

is a compound preposition.

Iteration stops when there are no more symbols to be referenced in the supplied package.
