can we have the struct field dynamic assign

[lydiandy]

can we have the struct field dynamic assign ,like this:

module main

struct Person {
pub mut:
	name        string
	age         int
	height      int
	description string
}

fn main() {
	//syntax one:this is best.
	mut mary := Person{}
	mary.name='mary'
	fields:=['name','age','height']
	person:=Person{name:'mary',age:19,height:180}
	
	for field in fields {
		mary.$field=person.$field //dynamically get and set the field of struct
	}
	//syntax two: the js syntax,may be is not best.
	mut mary := Person{}
	mary['name'] = 'mary'
	fields:=['name','age','height']
	person:=Person{name:'mary',age:19,height:180}

	for field in fields {
		mary[field]=person[field]
	}
	println(mary)
}

@lydiandy I don't get what you mean. Can you tell me when will this be useful and how?

[refrogerator]

I think he wants to access and modify a struct's field with the syntax of an array index.
It probably isn't very useful as we have

mary.name = 'mary'
mary.age = 33
mary.height = 180

I think V won't have runtime reflection (at least by default). Instead you will be able to generate statements at compile-time:

$for field in Person.fields {
	mary.$(field.name) = person.$(field.name)
}
// same as:
mary.name = person.name
mary.age = person.age
...
