Find examples of this not working due to dynamic dispatch

[oxinabox]

Jameson says this doesn't work for a bunch of cases.
Because of the fact that dynamic calls do not get edges attached.

But I am not sure it is possible to use this in a way that that matters.
I haven't been able to find any.

I need to create a few examples of them.for the docs

Does it work with @generated functions? or within macros more generally? Specifically, the @generated documentation calls out has_method as not being something you should use.

[oxinabox]

Should work in macros.
It won't work with in @generated functions, I don't think.
But it should work inside StagedFunctions.jl's staged functions.
