Description
The problematic cases are e.g.:
julia> using DynamicSumTypes
julia> struct B{T}
x::T
end
julia> @sumtype A{T}(B{T}, B{Int})
A
julia> @sumtype A2(B{T} where T, B{Int})

Research direction
Start by running the two Julia reproductions in the issue with DynamicSumTypes and inspect the @sumtype handling for variants sharing names across abstract and concrete parameters. Done means both reported problematic cases are handled without the described error, with behavior confirmed by tests if the repository provides relevant coverage.
