And returning to this a day later: I am now doubting we will be able make the definition of ops "static" (i.e. not needing to occur in the context of a `mlir.ir.Context`) as the `i32` that occurs in the examples above is actually `i32 = irdsl.Is(IntegerType.get_signless(32))` where `IntegerType.get_signless(32)` does (implicitly) require a `mlir.ir.Context` to be active. 😞
