It may be useful to restrict the scope of the file handle as well, since slurping is a one pass approach. That may be done with

my $string = do { local $/; open local(*FILEHANDLE), 'somefile.txt' or die $!; <FILEHANDLE> };
or, better if lexical filehandles are available,
my $string = do { local $/; open my $fh, 'somefile.txt' or die $!; <$fh> };
since the lexical handle is properly closed when it goes out of scope. Either way ensures no interference with other handles of the same name.
