Well, C. J. Date himself later changed his mind
(http://www.amazon.com/exec/obidos/tg/detail/-/0201543036/ref=ase_ffesoftwareinc/002-1731702-2750422?v=glance&s=books); I am inclined to agree with
his later optinions.

But that's not really the issue at hand. The issue is that "your"
proposal of a new operator makes a lot of sense and Firebird should
have it.
