Comment(by phk):

 PRIV_CALL works as it should work.

 The relevant question is if it should be used in std.fileread(), and if
 so, if it should be used the way it is now.

 Basically std.fileread() only looks at its argument the first time it is
 called and that probably breaks POLA pretty badly.
