No. That is a recipe for disaster. You are arguing that container types
(such as slices or maps) should be automatically converted. Such as is done
by the C language for primary types (e.g., char, int, etc.). But even C
does not allow implicitly converting one array type to another. You have a
misunderstanding of what `any` means. The `any` keyword is a shorthand for
`interface{}`. Any concrete type such as `int` is not equivalent to
`interface{}`. Which means that a slice of a non `any` type cannot be
magically converted to a slice of `interface{}`.
