9/2     How do I use a variable expansion in perl regex?  Something like
                $PATTERN = ".*foofoofoo";
                $_ =~ s/$PATTERN//g;
        Basically I'd like a C #define style expansion of $PATTERN.  TIA
        \_ The above should work. You might want to add the "o" flag to
           the s/// operator for efficiency if your $PATTERN doesn't change.
        \_ Also, you don't need to say "$_ =~ "; it's implied.
