The issue here is that the empty int list TupleInt.EMPTY is unified with TupleInt(0, partial(lambda i, self, j: Int.if_(j == self.length(), i, self[j])), 101, TupleInt.empty) aka TupleInt(0, lambda j: Int.if_(j == 0, 101, TupleInt.EMPTY[j])))

Now let's say we do a naive index the empty list like TupleInt.EMPTY[0]. We could say this incorrect, or how we can represent it is that it unifies with Int.NEVER. But it can show up in the e-graph, because in if_ conditionals, the false branch can end up doing indexing that is not allowed. So we want it to not mess things up.

And in this case then, it will evaluate to (lambda j: Int.if_(j == 0, 101, TupleInt.EMPTY[j])))(0) which is Int.if_(0 == 0, 101, TupleInt.EMPTY[0])) which is 101... So then what we get is that 101 is unified with Int.NEVER which... isn't good! Is really bad! Because it means all numbers can be unified together basically, i.e. false is true whatever.

  • since i guess i won't write another thing on here weeknotes wise till after xmas i hope you all have a fantastic one if you celebrate, and a great day otherwise too! happy solstice for tomorrow, even if you don't celebrate it too (brighter days are coming, northern hemisphere! the hateful sun is going back in her cage, southern hemisphere!) xo
