Or, more consistent, make auto foreach indices require "auto"?

int i;

foreach(auto i, auto j; something)
    writefln(i); // New local i which overrides outer i

foreach(i, auto j; something)
    writefln(i); // Uses outer i

writefln(i); // Writes the value that i last had in the loop

This has the (wonderful) side-effect of making it bleedingly obvious that 
the foreach indices are using type inference; the current index inference 
form _looks_ like it's trying to use already-defined index variables.
