--- Comment #2 from Dicebot <public at dicebot.lv> ---
Andrei, you may have been too quick to give a judgement without having a close
look what actually happens there.

All those @trusted functions exist there exact for the purpose of NOT marking
everything as @trusted but keeping actual function @safe. Those are used in
contexts where operation in general can't be verified to be @safe (and thus C
binding can't be marked @trusted itself) but it is verified in specific context
where it is called. Wrapping such call in trivial @trusted function allows to
keep everything else @safe and enjoy compiler verification.

I do immediately see that some of those posix functions could have been marked
as @trusted in extern(C) binding itself - and should probably be removed to
reduce visual noise and simplify maintenance.

However, there is nothing fundamentally broken with that code in context of
type system and language itself.
