Why doesn't Perl file glob() work outside of a loop in scalar context?

Question

According to the Perl documentation on file globbing, the <*> operator or glob() function, when used in a scalar context, should iterate through the list of files matching

Answer 1

Also from perlop:

A (file)glob evaluates its (embedded) argument only when it is starting a new list.

Calling glob creates a list, which is either returned whole (in list context) or retrieved one element at a time (in scalar context). But each call to glob creates a separate list.
