Lies in descriptions of ${Xmeta as ...}

In tpo/core/arti!1158 (closed) I observed:

My first cut failed the tests because I had omitted .. as lit on the use of ${meta(display)}. See the code comment about this. I had to use the dbg feature to diagnose it.

But the docs in reference.md say:

lit: A literal value; expands LIT directly; equivalent to not having said as.
