-- Helper vars:
---------------
-- These variables are only used by the init functions.
-- Therefore, even though they are re-assigned every time
-- a new instance is created (through `new()`), there's no
-- problem, because their useful lifetime is only inside
-- that very function.
-- This way, having them here kinda as static variables,
-- supports encapsulation, since each instance of `File`
-- doesn't need to have them.
