There is no guarantee about how many times `ToLiquid` will be called.

A `[]byte` is not (currently) equivalent to a `string` for all uses; for example, `a < b`, `a contains b`, `hash[b]` will not behave as expected where `a` or `b` is a `[]byte`. - MapSlice - - An instance of yaml.MapSlice acts as a map.
