Re(5): Toggling between two values

[chip]

Well, hm. Given this behavior:

eval q{ my $foo = 1; sub bar { ++$foo } };
print &bar, &bar, &bar;

Would you say that &bar is a closure? Because if it is, then I've been conflating closures in general with a specific subset of them, and I have some apologies to make....
