string interpolation does not correctly reports pointer when used with maps

[thomas-mangin]

Describe the bug

When using string interpolation with maps, the element printed is returned as a value the & of the pointer is not included in the returned string.

Reproduction Steps

module main

struct Inner {
	value int
}

struct Outer {
	value map[string]&Inner
}

fn main() {
	outer := Outer{
		value: {
			'test': &Inner{
				value: 1
			}
		}
	}
	unexpected := "Outer{
    value: {'test': Inner{
        value: 1
    }}
}"
	expected := "Outer{
    value: {'test': &Inner{
        value: 1
    }}
}"
	assert '${outer}' == unexpected
	assert '${outer}' == expected
}

Expected Behavior

the expected string of the example to be returned

Current Behavior

the unexpected string of the example is returned
