I think in D2 the attributes like const and immutable for classes/structs (and
maybe enums too) can be moved on the right, but this program:

class Foo {
    auto bar1() const { return 0; }
    auto bar2() immutable { return 0; }
    auto bar3() shared { return 0; }
}
struct Spam {
    auto baz1() const { return 0; }
    auto baz2() immutable { return 0; }
}
void main() {}


Generates some errors (dmd 2.042):

temp.d(2): no identifier for declarator bar1
temp.d(2): semicolon expected, not 'const'
temp.d(2): Declaration expected, not 'return'
temp.d(3): no identifier for declarator bar2
temp.d(3): semicolon expected, not 'immutable'
temp.d(3): Declaration expected, not 'return'
temp.d(4): no identifier for declarator bar3
temp.d(4): semicolon expected, not 'shared'
temp.d(4): Declaration expected, not 'return'
temp.d(7): no identifier for declarator baz1
temp.d(7): semicolon expected, not 'const'
temp.d(7): Declaration expected, not 'return'
temp.d(8): no identifier for declarator baz2
temp.d(8): semicolon expected, not 'immutable'
temp.d(8): Declaration expected, not 'return'
