I want to know, too :)

I think it depend on version of Perl.
My test environment has 2 different version of Perls.
The following is my test result, that says
version 5.005_03 allows glob to invoke shell,
but version 5.6.1 does not allow.

# /usr/bin/perl -v | grep This
This is perl, version 5.005_03 built for i386-linux
# ls /tmp/g*
ls: /tmp/g*: No such file or directory
# /usr/bin/perl
files=<*.h; /bin/touch /tmp/glob_test_1>;
# ls /tmp/g*
/tmp/glob_test_1
# /usr/local/bin/perl -v | grep This
This is perl, v5.6.1 built for i686-linux
# /usr/local/bin/perl
files=<*.h; /bin/touch /tmp/glob_test_2>;
# ls /tmp/g*
/tmp/glob_test_1
