struct Product {
mut:
	schema1 []string = ['id']
	schema2 []string = ['sku']
}

pub fn (p Product) do_somthing() Product {
	mut schema := p.schema1
	schema << p.schema2
	return p
}

fn  main() {
	mut p := Product{}
	println(p.do_somthing())
}

What did you expect to see?

Addendum
With:

mut schema := p.schema1.clone()

The code works well.

The clone() is missing, and the error should be the same than:

module main

fn  main() {

	schema1 := ['id']
	schema2 := ['sku']

	mut schema := schema1
	schema << schema2
}

get error like:

test/bug.v:8:13: error: use `array2 := array1.clone()` instead of `array2 := array1` (or use `unsafe`)
    6 |     schema2 := ['sku']
    7 | 
    8 |     mut schema := schema1
      |                ~~
    9 |     schema << schema2
   10 | }
