in reply to question about star character in Perl

The * sigil refers to Typeglobs and Filehandles. In this case, the author wanted to pass the newly-opened XML filehandle into a subroutine, and old fashioned Perl didn't have a particularly clean way to pass one. Nowadays, you'd probably write that as:

open (my $XML, "<", $xml_file) or die "File open failed ($xml_file): +$!; get_data($XML, \%hash);

The indirect filehandle makes passing and stashing much cleaner (IMHO). See also open and Indirect Filehandles in perlopentut.

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.
