Fellow Monasterians:

I have an array where I want to eliminate all the elements between, and including, the two starting and ending elements. So, in my example below, I'd like to end up with a @array of one 1{ two } three six, eliminating 2{ four five }. I found a way (thanks to Q&A), but it looks rather clunky (and I get a "Use of initiated value" in my second regex test). Is there a shorter way, like grep or map (though I like this one because it doesn't create a new array)? Golf anyone?

#!/usr/bin/perl -w

use strict;
my @array = qw( one 1{ two } three 2{ four five } six );

my $i = 0;
my $start;

while ( $i <= $#array ) {
   if ($start && $array[$i] =~ /}/) { 
      splice @array, $i, 1;
      undef $start;
      $i++;
   }
   if ($start || $array[$i] =~ /2{/) {
      $start = 1;
      splice @array, $i, 1;
   } else { 
      $i++;
   }
}

print @array;

Thanks all!
