Here is a MWE that doesn't use any of my internal code
julia> struct Foo{T}
end
julia> (this::Foo{T})(args...) where T=1
julia> SciMLBase.isinplace(Foo{Int}(), 4)

I am running into an issue very similar to https://github.com/SciML/SciMLBase.jl/issues/268 I suspect the cause is very similar, though the packages involved are different. And I can't tell it manually because the particular case I am hitting is for
jac
which also hasisinplace
used on it, but which doesn't have a way to manually say it is inplace or not. It is due tomethods(f).ms[1].sig.parameters)
