So a part answer is something along this line: ``` function aliased(a::T, b::T) where T a === b end function recursive_aliased(a::T, b::T) where {T} if aliased(a, b) return true end...

A slightly better version is ```julia begin function recursive_aliased(a::T, b::T, seen_a::IdSet{Any}, seen_b::IdSet{Any}) where {T} if aliased(a, b) return true end if a ∈ seen_a return false elseif b ∈ seen_b...

@aplavin sorry for the ping :) We should have that conversation on Slack. The ting I was looking for was recursion over two objects of the same type (and structure)...

@wsmoses mentions that this should never be the `parent_scope(val) isa LLVM.Module`
