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.

This, deep down, point at the fact that conversion from/to char
types are ill defined.
One should be able to convert from char to byte/ubyte but not the
other way around.
One should be able to convert from byte to short but not from
char to wchar.
Once you disable the naive conversions, then the autodecoding in
foreach isn't inconsistent anymore.
