Syntax is the main issue in implementing this feature. Due to the

FWIW I just thought of this syntax. It might work but it's not intuitive:
const()C tailConst;
Syntax was not the issue. Back when we tried hard to make this work, there were
many syntaxes proposed for it. The issue is the semantic conflation between a
reference and what it refers to.
