How to handle Option in the case of multiple return values?

[hellolio]

fn main() {

	a, b := foo()
	a1 := a or { -1 }
	b1 := b or { "qqq" }
	println('a: ${a1} b:${b1}')

}

fn foo() (?int, ?string) {
	return none, 'eee'
}

In the case of immutability, I have to name two new variables(a1,b1). Is there a better way to handle this?

No. V doesn't do tuples, it does multi-returns, and each return value must be handled separately.

I would appreciate suggestions on how to avoid using a1 and b1.

[JalonSolov]

Easiest way is to declare a and b as mutable.

Otherwise, you either need to create the extra variables, or do the check every time you use a or b.

[JalonSolov]

If the names a1 and b1 offend you, assign the returns from foo() to dummy vars, then use a and b instead of a1 and b1...

fn main() {
	foo_r1, foo_r2 := foo()
	a := foo_r1 or { -1 }
	b := foo_r2 or { "qqq" }
	println('a: ${a} b:${b}')
}

fn foo() (?int, ?string) {
	return none, 'eee'
}

Thank you for your response. I think this is the only option we have for now. I will close this discussion.
