foreach(static i;0..42) doesn't work either, and 'static' is a storage 
class.

'immutable' is a type constructor besides being a storage class.

The attributes allowed in `foreach' are those that are considered to 
make sense, and they are specified in the grammar: 
http://dlang.org/statement.html#ForeachTypeAttributes

Furthermore, both of those declarations are valid:

static i = 2;
immutable j = 3;

What is important is that the type was left out, not that it was 
replaced by 'auto'.
