While coding something today I came across an interesting question regarding coding styles. Say you have a test you need done in which, when successful/unsuccessful, you exit the script completely AND after that test is done, you do something else.

Easier asked with an example, I s'pose.

my $name = param("name");

if ($name eq "")
{
   print qq(Sorry, name can't be empty);
   exit;
}

print "Thank you, $name. Your submission is complete.";

How many of you exclude the else clause in the above situation? 
if ($name eq "")
{
   print qq(Sorry, name can't be empty);
   exit;
}
else
{
   print "Thank you, $name. Your submission is complete.";
}

Can anyone think of a reason why the first example could be a bad idea under given circumstances? I can't see how either would be better or worse, but am curious to see how you guys would perform simple tests like this.
