Another potential example is
#+CONSTANTS: valC2=299792458.
and then $valC2 reference.

Currently, the order of reference expansion is undefined. So, it is
_technically_ not a bug, but undefined behavior.

However, it is indeed confusing.
So, we may consider specifying the order of reference expansion.
But what should be that order? We need to think about all possible
expansions and how they might interact in edge cases (e.g. what if we
have :CrazyPropertyName@1$2:)

Also, it is confusing that the manual does not clearly explain that "B4"
expansion only happens when editing formulas interactively via formula
editor.
