256ish troubles #37
Description
There appear to be bugs that go away when you restart julia.
See https://github.com/oxinabox/MagneticReadHead.jl/issues?utf8=%E2%9C%93&q=label%3A256ish
This is most likely related to
JuliaLabs/Cassette.jl#6
and will all be solved when that is solved.
But we might be able to do better with some well placed invoke_latests.
Or possibly by changing how we create the Cassette contexts.
