Comment (by jdemeyer):
In these 3 cases, why don't you use the corresponding `biseq` functions?
{{{
return mpn_cmp(cself._path.data.bits, other._path.data.bits,
cself._path.data.limbs)
}}}
{{{
cdef mp_limb_t* p = self._path.data.bits
for i from self._path.data.limbs>i>=0:
h0 = h
h += deref(postinc(p))
if h<h0: # overflow
preinc(h)
}}}
{{{
out._path.itembitsize = itembitsize
out._path.mask_item = limb_lower_bits_up(itembitsize)
out._path.length = length
if length>0:
sig_on()
bitset_init(out._path.data, 1)
bitset_unpickle(out._path.data, bitset_data)
sig_off()
}}}
(and the corresponding `bitset_pickle()` of course)
