For variants you have:

type, t ::= ... | `id | `id of t | `id of & t | t & t

<< `id >> was encoded as RfTag(_loc, true, [])
<< `id of t1 & ... & tN >> by RfTag(_loc, false, [t1; ...; tN])
<< `id of & t1 & ... & tN >> by RfTag(_loc, true, [t1; ...; tN])

However I suggest you comment that part and try to go further with
poly variants at a first glance.
