No lexical, please. It would be worse, than order in which 
elements are declared.

At least with the later, you could also use it for some 
meaningful order, such as first declared takes priority for some 
action, or etc. Having it all sorted lexical would hinder it. 
Besides, lexical ordering can also be done already at compile 
time.
