The strict pragma does three things in Perl.  Two of the items are to  
forbid the use of symbolic references and "barewords."  Ruby doesn't  
support these features, so it's not an issue.

The other feature of the strict pragma is to avoid creating random  
global variables every time one is mentioned.  In Ruby, globals look  
different from other variables (the leading $), so this is not really  
a problem.  Local variables need to be assigned to before use, since  
that's Ruby's method of declaration.  That solves the same problem  
the strict pragma handles for Perl.
