Aha vs. Doh Can't Post

What does the following code print and _why_?
----------------------Cut-------------------------------
print "aha\n" and exit if (my $foo = 1 and $foo == 1);
print "doh\n";
----------------------Cut-------------------------------

It prints "Doh",

Becaaaaause, $foo != 1, it isn't defined.

That's a great one, :)

Yes, sleuth, you are correct!

'my $var' declarations do not become "visible" until after the current statement...
