Yeah. I was actually thinking more of something like:

<table_identifier> RECURSIVE JOIN ON <column_expression> <operator> 
<column_expression>

... which would be a pretty good simplest-case syntax.

When I mentioned connect_by() I was referring to Joe's function, not 
Oracle's syntax, which I think is awful.
