The do FILENAME construct does not work if the last line in the file does not end in a newline. Bug or feature? For example, the program 

use strict; use warnings;
my $do_me="do_me.pl";
foreach my $ending ('',"\n") {
  print "Create file with",($ending?'':'out')," newline\n";
  open(OUT,'>',$do_me) or die "$!";
  print OUT "q(string)$ending";
  close OUT;
  my $result=do $do_me;
  print "Can not read $do_me: $!\n" if $!;
  print "Can not evaluate $do_me: $@\n" if $@;
  print("$result\n") if defined $result;
}

produces as output 
Create file without newline
Can not read do_me.pl: Bad file descriptor
string
Create file with newline
