Hi Meikel, Rich,
Thank you for your clarification.
Now I understand the difference between #^ and with-meta and I can see
#^metadata on a seq form is intact at compile time (and it can be
passed down to runtime) so that now I know I was wrong to say like the
topic.
Thanks again.

It is called "case equality" which is a terribly confusing way to say
"the predicate used to match in case statements". "Match" is really
the best verb. In Ruby, most things match by value equality. But
classes match their instances. Ranges match things in the range.
