Yes they should always come in lexical order.


For classes, the spec disagrees, even though it might be true 
using current compilers.


https://dlang.org/spec/class.html#fields

"The D compiler is free to rearrange the order of fields in a 
class to optimally pack them in an implementation-defined manner. 
... Explicit control of field layout is provided by struct/union 
types, not classes."

When using reflection to obtain the fields of a class/struct, is there 
any guarantee that the order is the same as the order the fields are 
defined?
