Is it possible to switch the line terminator for reading files in the middle of a program based on scope? I'm reading files that tend to have lines that span more than a single-line. So to do that I simply undef $/; Is it possible for me to redefine the line terminator once it's been undef'ed? I can't seem to get the $/ scoping to work, so once i have it undef'ed, i can't revert it. so... 
#!/usr/bin/perl

undef $/;

&doStuff();
&foo();

sub doStuff {
   # want to read the file as a single string....
   open TMP, "<somefile.txt";
   my @file = <TMP>;
   close TMP;
   # do more stuff with that file...
}
sub foo {
   ## here i would want to read the file line-by-line
   
   $/ = '\n';
   open TMP, "<otherfile.txt";
   my @file = <TMP>;
   close TMP;


}
