Complex regex

Question

Consider the following regular expression:

^[:;][-^]\)$

List all lines that exactly match this expression, or if there are more than ten such lines, describe them.

Answer 1

Assuming the closed guy is false, here is a smooth solution:

% echo {':',';'}{'-','^'}\)
:-) :^) ;-) ;^)

What of course:

% perl -le 'print for <{:,;}{-,^})>'
:-)
:^)
;-)
;^)

Isn't that cool?

And then, of course, this is what:

              #!/usr/bin/perl
          use            5.010                                                                                     ;
        $stdout = 124.102.109.116;
                 open
                stdout                                                                                             ;        
              use    less 
  ${"\42"}         =         "\54"                                                                                 ;
                  say 
                  for 
                 @224                                                                                              = 
                  eval 
                  join 
                /\/\/\/∖/                                                                               => 
                   map 
                {"<$_>"} 
                  join 
                /\/\/\/∖/                                                                               => 
                   map 
                {"{@$_}" } 
           [qw{  |  [     }   ]                                                                                    =>
       [qw{    :  ;  % #     }   ]                                                                                 =>
   [qw{      ^  =  *  _  ~    }    ]                                                                               =>
[qw{     /  v  )  |  o   3  I   }    ]  

which delightfully produces this:
