OK, I'm stumped. I'm trying to read from a file handle in a while loop. The reference to the file handle is in a hash which itself begins with a hash reference like this ... 
my $cfg = {};
open (INFILE,"<testfile.txt") || die "Could not open file\n$!\n";
$$cfg{infile} = \*INFILE;

while(<$$cfg{infile}>){
    print "$_\n";
}
__END__
GLOB(0x20eab18)

However, when I do it this way, it works as expected. 
my $cfg = {};
open (INFILE,"<testfile.txt") || die "Could not open file\n$!\n";
$$cfg{infile} = \*INFILE;
my $infh = $$cfg{infile};

while(<$infh}>){
    print "$_\n";
}

I figure that the angle operator is not dereferencing $$cfg{infile} as I want but I cannot come up with a combinations of parens, curly braces and arrows that will make this work. What am I missing?

Update: I knew I was missing the obvious. Thanks Roy. :o)
