Leading dot notation should not appear in insert shapes

[zchenb]

The following query should not be compiled and executed successfully:

insert Person {name := "<name>", friends := .friends};

[zchenb]

This seems fine:

insert Person {name := "t1", dname := .name};

So not really a issue?

It may also be used in the case of schema computables.

Another interesting case:

Schema:

type Test2 {
    d1 : str ;
    d2 : str {
        default := "d2" ;
    }
    d3 : str {
        default := .d2
    }
    d4 : str {
        default := .d3
    }
    d5 : str {
        default := .d4
    }
}

Query:

insert Test2 { d1 := "6", d3 := "fe", d5 := .d2};
insert Test2 { d1 := "7"};
insert Test2 { d1 := "8", d3 := "fe"};

Result:

default::Test2 {id: 4c64eec6-d96c-11ed-be7f-77285a6a60ff, d1: '6', d2: 'd2', d4: 'fe', d3: 'fe', d5: {}},
default::Test2 {id: c786c4e4-d96c-11ed-afc5-ff76c51d0376, d1: '7', d2: 'd2', d4: 'd2', d3: 'd2', d5: 'd2'},
default::Test2 {id: e41bb7ae-d96c-11ed-afc5-673d47b6bf08, d1: '8', d2: 'd2', d4: 'fe', d3: 'fe', d5: 'fe'},

Does not make any sense to me how d5 could possibly be {}
