Then there is a "dent" in the documentation:

until

Examples: 

        until sunrise
          sleep
        end

Syntax: 

        until expr [do]
          ...
        end

Executes body until condition expression returns true. 

which is quoted from ruby-man-1.4/syntax.html#until
I could not get it to work with do 
ruby> i = 0
0

ERR: (eval):1: compile error
