... a value that is not the empty string and matches the pattern  /^[a-zA-Z]*[0-9]*\z/ ...

This part of the documentation is confusing to me because the empty string matches the pattern:

"$_ = '';
 print 'match' if /^[a-zA-Z]*[0-9]*\z/;
"
match

I'm sure I've seen a discussion of this point, but I cannot lay my hands on it at the moment. Anyone...?
