Unhelpful suggestion when trying to pass array expr to var args

[thetarnav]

SQUARE :: [4][2]f32{
	{0, 0},
	{1, 0},
	{0, 1},
	{1, 1},
}

points: [dynamic][2]f32

append_elems(&points, ..(SQUARE * 100 + 100))

/* Error:
	Cannot assign value '(SQUARE * 100 + 100)' of type '[4][2]f32' to '[][2]f32' in a procedure argument
	Suggestion: The array expression may be sliced with (SQUARE * 100 + 100)[:]
*/

append_elems(&points, ..(SQUARE * 100 + 100)[:])

/* Error:
	Cannot slice array '(SQUARE * 100 + 100)[:]', value is not addressable
*/
