This little bit of code gave me the RCA dog look for a while. After thinking
it through, it made sense.
If references are not your strong suit, then read on.
What will the final print statement say for each of these snippets?
$hash = {1=>one, 2=>two, 3=>three};
$list = [fred, barney, $hash, wilma];
$hash = {1=>ONESIE,2=>TWOSIE,3=>THREESIE};
print STDOUT "value is:'$$list[2]{2}' " # is it 'two' or 'TWOSIE'
$hash = {1=>one, 2=>two, 3=>three};
$list = [fred, barney, $hash, wilma];
$$hash{2} = TWOSIE;
print STDOUT "value is:'$$list[2]{2}' " # is it 'two' or 'TWOSIE'
__END__
So what is it?
Just another of my little Perl pseudo-gotchas...
