The main places where it's safe not to use the double quotes are:

• in an assignment: foo=$bar (but note that you do need the double quotes in export "foo=$bar" or in array assignments like array=("$a" "$b"));

1. Why is it not required to double quote $bar in assignment foo=$bar?

2. Why do we need the double quotes in export "foo=$bar" and in array assignments like array=("$a" "$b")?

Thanks.
