Wow, so many complicated solutions! It's actually quite simple:

  1. Find start of opening bound, then
  2. Find start of data, then
  3. Find start of closing bound 
my ($seen_opening, $seen_data, $seen_closing);
my @filtered =
   grep
      {     ($seen_opening ||= /DBIC/)    # Find opening bound
        &&  ($seen_data    ||= !/DBIC/)   # Find data
        && !($seen_closing ||= /Dancer/)  # Find closing bound
      }
      @list;

Using the range operator is possible too. 

my @filtered =
   grep { (/DBIC/ .. /Dancer/) && !/DBIC/ && !/Dancer/ }
      @list;

Update: Added range operator solution.
