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.

It does not work for wrapped python functions:

using PyCall
using Tricks
py"""def f(x): return x
"""
f = py"f"
static_hasmethod(convert(Function, f), typeof((1,)))
# ERROR: UndefRefError: access to undefined reference

(of course I do not expect it to be able to infer the actual arguments for the python function, but it would be nice if it successfully returned the value it should for convert(Function, f) (which should be true) or errored in a nicer way)
