      he/she almost answered it.
      while ($line .= <Stream>) 
{ 
  exit if ( $line =~ m/b\n*l\n*a\n*h/m); 
}

        He/She did not understand the scope of the request. Probably the posted request was not too clear.

        I don't want to match things on a line by line only and I don't want to modify $/ to read other types of chunks of text. Just set $/= undef.

        The deeper problem is how to apply a regular expression with multiple matches options to a stream so I don't have to load large pieces of the file and to re-start the reglar expression if it fails.

        So far one of the suggestions makes possible sense... if the regex engine can be tricked into working with an expanding buffer.
