@WG-prioritization issue #70813 has been requested for prioritization.
P-low as it requires a custom rustc build and goes from error to error + ICE
I would like someone familiar with NLL (@Matthew Jasper or @nikomatsakis I guess) to take a look to make sure it's not that we're not detecting some bug on regular compilers because debug asserts are off
but other than that, yes, seems p-low
Issue #70813's prioritization request has been removed.
