> We had a long-standing issue CAY-2034 with an idea to support various
> non-alphanumeric chars in db: and obj: paths. Such an implementation would
> require an escape syntax. How about we go after a low-hanging fruit first -
> support "$" in both expressions. "$" is a valid Java identifier character
> after all, and is in fact used in the code:
> https://docs.oracle.com/javase/8/docs/api/java/lang/Character.html#isJavaIdentifierStart-int-
> https://docs.oracle.com/javase/8/docs/api/java/lang/Character.html#isJavaIdentifierPart-char-
> Hopefully this will not require escaping.
