But the way I'm looking at English, it really has ways
of marking the equivalent of direct and indirect objects,
by position or preposition. So in that sense, and I assume
all Romance langs are the same, they have the 3 "core" cases
(plus a genitive) well-covered. Whereas:

My conlang has no means of providing a "dative" or "direct object",
and only distinguishes subject/object by putting the verb in-between,
and genitive by *not* putting a verb between noun phrases. To say
"I told you about it" requires a serial verb construction.
