more often as well.

You'll need to be more specific. We are simply limiting the first SFT of a nested struct out of the partitioner, instead of recursing into MPT elements during operand scanning.

Where is the extra compile time coming from? Are we generating that many more virtual operands? It would help quite a bit if you'd open a PR with a testcase for me to reproduce this behaviour.


Thanks. Diego.
