Scalar variables have to stay scalar in list context, so $dance cannot
suddenly start behaving like a list. Something must tell the scalar
to behave like a list, and I don't think I want C<for> to do that.
A C<for> should just take an ordinary list.
So you can do it any of these ways:
for <$dance> {
for $dance.each {
for each $dance: {
^ note colon
Then there's this approach to auto-iteration:
my @dance := Iterator.new(@squares);
for @dance {
