Visual Basic (and VBA, and VBScript) have it, too.  Again, same
spelling for the keyword, but attributes of the 'with-ed' object
are spelled with a leading dot.  Nested with's are allowed, but
the outer one[s] are not "active" within an inner one -- e.g., in:
    with fee
        with fie
            .foo = .fum(23)
        end with
    end with
both the .foo AND .fum references MUST be to attributes of
object fie -- there is NO role implicitly played by object fee
in this case.
