when bar depends on foo; such as a user defined cond, lets saya 
database query that takes in lamdas

`foo?=a=>a%2:baz`

and when its "multiable data single instruction", simd or 
parrellizism, ranges etc. and theres something in that index
you can not write `if(!bar[foo's slice????]) foo=baz[...];`
