I understand where you're coming from, but it actually is autodecoding. 
Consider:

byte[] a;
foreach (byte x; a) {}
foreach (short x; a) {}
foreach (int x; a) {}

That works by means of a conversion short->int. However:

char[] a;
foreach (char x; a) {}
foreach (wchar x; a) {}
foreach (dchar x; a) {}

The latter two do autodecoding, not coversion as the rest of the language.
