 ## Well this test script was propted by a query on File::Slurp and la
+ter file slurp which led me to 'Slurp a file' (http://perlmonks.com/i
+ndex.pl?node_id=50525) by AnonymousMonk:

Description: Slurp a file into a scalar. Jean-Daniel Gamache webmaster
+@perls.org

open (IN, "<myfile.txt");
{local $/; $file_content = <IN>;}
print $file_content;

## Then davorg (man with the munchies) replies with:

Oops. You've just left $/ set to undef for the rest of the program. Th
+is can lead to all sorts of nastiness.

Better to do something like this:

my $file_text;

{
  local $/;
  $file_text = <FILE>;
}

print $file_text;

Which returns $/ to its original value once you leave the bare block.

## This really had me confused.
The original post had a block, it doesn't matter (and 'the Rock' chime
+s in 'It doesn't matter!') where you declare $file_content, as it has
+ no bearing on local or $/ since {;;;;;} is a valid block!....

I was kind of in doubt of my faculties for a split second, and then I 
+scrolled down the page, and found an AnonymousMonk node saying "Sorry
+, you were right!"

Then it came to me (in a vision =;:): davorg had been coding drunk aga
+in.
  ... there's always a valuable lesson to be learned ... keep (c|n)ode

# some quick test code

print '$/',"is = '$/';\n";

    {
        local $/; # in effect, makes $/ uninitialized
        print '$/',"is = '$/';\n";
        print <DATA>;

update: Hmmm, I saw no mention of that, oh well: "you live you die, it's all for perl and peanuts ;-)".
