This won't work in D. Everything that's static is common to

What's possible however is to use an immutable FState that's
set in the ctor.

struct File

immutable FState state,
this(string fname, FState st){state = st}

Than you're sure that your file state can't be changed by
error.
Otherwise just hide the state to set it as a private
variable...
No, I'm talking about adding a new feature to the language,
modifable enums(typestate).
Ok, sorry I didn't know this concept so far.
So there would be a kind of 'compile-time instance' of File with
a modifiable member ?
