No, back in 7.1.0 I was able to call CURRVAL without having previously called
NEXTVAL, and it would give me the "current" sequence value; that is, the same
result value as (NEXTVAL() - 1); I wouldn't mind having a new function that
does this; I can understand making a distinction between the pre-session
CURRVAL, and the general current value.

Me, I use functions.
