C error: error in conversion

[Linklancien]

Describe the bug

/home/bleiz/v/vlib/rand/rand.v:508: error: cannot convert 'struct _result_main__Condition' to 'struct _result_anon_fn___bool'
builder error:
==================
C error found. It should never happen, when compiling pure V code.

Reproduction Steps

import rand

type Condition = fn () bool

fn main() {
	mut list := []Condition{}
	list = [fn () bool {
		return true
	}]
	println(rand.element[Condition](list) or { panic('Err') })
	println(list)
}

Expected Behavior

This shouldn't cause a C error

Current Behavior

C error

Possible Solution

No response
