Hi,

Can StgRhsClosure's freevar list ([occ]) or argument list ([bndr]) contain duplicates?

Cheers,
Csaba

data GenStgRhs bndr occ
  = StgRhsClosure
        CostCentreStack         -- CCS to be attached (default is CurrentCCS)
        StgBinderInfo           -- Info about how this binder is used (see below)
        [occ]                   -- non-global free vars; a list, rather than
                                -- a set, because order is important
        !UpdateFlag             -- ReEntrant | Updatable | SingleEntry
        [bndr]                  -- arguments; if empty, then not a function;
                                -- as above, order is important.
        (GenStgExpr bndr occ)   -- body
