You could write a little wrapper function to do that

uint myformattedRead (R, Char, S...)(R r, const(Char)[] fmt, auto 
ref S args) {
     formattedRead(r, fmt, args);
}


It just strips the ref off of the input string but otherwise 
forwards the same thing.

The reason it is ref tho btw is that that allows it to continue 
off a particular input; you can do like

string s;
formattedRead(s, ....)
formattedRead(s, ....) // this one picks up where the last one 
left off
