http://dlang.org/phobos/std_stdio.html#readf

why readf do not use reference ? as :

uint readf(Data...)(in char[] format, ref Data data); 


it is not possible? I think this little thing could enhance to have a D
cohesive syntax. Of course D support pointer but ref is more in D spirit and
point C spirit. They are not many phobos function where need a pointer or an
address.


Thanks, i hope my talk is not stupid

kind regards

When readf was defined, ref didn't work with variadics. Closing because fixing
behavior now would break existing code.

Maybe a less bug prone and different named function should be added, that uses
ref...

Actually it's not that bad - readf is not bug prone because it statically
ensures that all of its parameters are pointers. Using pointers is also safe
because readf doesn't escape them. Actually I'm reopening this with a different
title.
