Let me ask a related question: if there were a priority list of

For once, I agree with Bearophile. The adjacent string
concatenation was
a very very early feature, and the ~ completely supplants it. While I
don't think it causes many problems, it's a pointless redundancy and
should be removed.
I agree too but there are many similarly good ideas (some of which
from himself) that are older.

This isn't new. I remember this one being discussed about seven years
ago.
Well put me on board then. Walter, please don't forget to tweak the
associativity rules: var ~ " literal " ~ " literal " concatenates
literals first.
You mean *should* concatenate literals first? I think currently it doesn't.

Yah, "shall" as they say in Standardese :o). Currently it doesn't, but
you get to catenate literals by juxtaposition. For example, this expression:
s ~ "def" "ghi"
when naively changed to
s ~ "def" ~ "ghi"
will do more work than before. We must avoid that.
