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.

It was a syntactic issue. Semantically it is self-evident what operation
is on the reference itself vs. the referenced data.
