Perl interprets that command like this:
print func(*5, "\n");
The "*5" and "\n" become parameters to func. Change the code like this:
print func() * 5, "\n";
Or you could change the function like this:
sub func() {
return 10;
}
This is the one time where prototypes can be used without messing things

See `perldoc perlsub` and search for the section on "Prototypes".
